INTRODUCTION
Thank you for your purchase of a Fisher Science Education microscope. Your new microscope
is a precision instrument carefully checked to assure that it reaches you in good condition. It is
designed for ease of operation and years of carefree use. The information in this manual probably far
exceeds what you will need to know in order to operate, troubleshoot and maintain your microscope.
However, it is provided to answer questions that might arise, and to help you avoid any maintenance
expense that may be unnecessary.
TYPES OF MICROSCOPES COVERED IN THIS MANUAL
The compound microscope combines two optical lens systems. The lens closest to the specimen
slide, the objective, magnies the primary image and the top lens, called the eyepiece, further
magnies the image. Magnication of the objective times the magnication of the eyepiece is the
total magnication produced by this combination of lenses. The image produced by the compound
microscope is upside down and reversed. Compounds are used for viewing standard 1” by 3” 1mm
thick transparent specimen slides with cover slips. Prepared specimen slides can be purchased to t
the classroom subject matter or user can make his own specimen slides.
The stereo microscope is an instrument that incorporates two separate optical system aligned to
produce three-dimensional images. Primary uses of the stereo microscope are the inspection and
assembly of small parts, examining plants and insects, dissecting of biological specimen. Stereo
microscopes provide an upright, unreversed image that permits easy manipulation of the object being
viewed while looking through the microscope. Stereos are designed for viewing solid objects at low
magnication, but they will also permit viewing of some transparent specimen slides.
Digital microscopes have all of the features of a compound microscope or stereo microscope but
are enhanced with the addition of a built-in digital camera. With software included with these digital
microscopes, they become real time learning tools.

MICROSCOPE TERMINOLOGY
• ABBE CONDENSER: The 1.25 N. A. Abbe condenser lens positioned under center of stage is
requited when using 100x objective lenses. In addition the Abbe condenser is focusable by one
of two methods, a spiral mount condenser with lever to lower or raise the assembly or else a rack
and pinion mount with a knob to provide movement in the up and down direction
• ARM: Main support for microscope components.
• BASE: Housing and platform of the instrument to which the arm is attached in addition it usually
contains an illumination system for the microscope.
• BODY TUBE: On simple vertical tube models it holds the eyepiece tube and objective, on
advanced models it holds nosepiece, objectives and head.
• COAXIAL FOCUSING KNOBS: Coaxial focusing system combines both the coarse and ne
focus into one set of knobs located on the same axis. The control is designed for a continuous
operation over the range of stage movement.
• COARSE FOCUSING KNOBS: Large knobs located on each side of arm, raise or lower stage to
bring specimen image into focus.
• CONDENSER LENS (0.65): Condenses light rays from sub stage illumination and lls the back
element of objective lens to improve image resolution. A 0.65 condenser lens xed in center of
stage is provided on microscopes with objectives up to 40x (400 times magnication).
• DIOPTER ADJUSTMENT: Adjustable eyepiece diopter permits focusing adjustment of image for
any difference in vision between users eyes.
• DISC DIAPHRAGM: Disc located below stage with holes of various apertures, designed to help
achieve optimum resolution of the objective lens. Larger apertures used for higher magnications,
and smaller apertures used for lower magnications.
• EYEPIECE (ocular lens): Lens closest to the eye magnies the primary image formed by the
objective lens.
• EYEPIECE TUBE: This is the component that holds the eyepieces in place. Elementary, student
and high school models have set screws in the eyepiece tube used to lock eyepieces in place.
• FIELD OF VIEW: View area that is seen through the lens system of the microscope.
• FILTER: Daylight blue lter designed to make incandescent illumination appear white.
• FILTER HOLDER: Attached to bottom of iris diaphragm that swings out allowing user to insert
lter of choice. If a built in neutral lter is provided it should be removed from the optical path
when using 40x and 100x objectives.
• FINE FOCUSING KNOBS: Smaller knobs, located close to the coarse focusing knobs, permit
more precise adjustment of the image.
• FOCUSING EYEPIECE TUBE BINOCULAR HEAD: Focusing eyepiece tube models, (two
diopters) used to adjusting parfocality and focusing adjustment of image for any difference in
vision between eyes.
• HEAD: Upper portion of the microscope which contain prisms and eyepiece tube or tubes.
• INCIDENTAL ILLUMINATION: Primarily used on stereo type microscopes to provide illumination
from above the specimen.
• INTERPUPILLARY DISTANCE: Interpupillary distance (IPD) is the distance between the center
of the pupils of the two eyes. Interpupillary distance is critical for the design of binocular viewing
heads so that the left and right image can blend into one image.

5
• IRIS DIAPHRAGM: Iris Diaphragm, opening and closing of iris is controlled by lever. It is
designed to help achieve optimum resolution of the objective lens. Larger apertures used for
higher magnications, and smaller apertures used for lower magnications.
• MAGNIFICATION: Total magnication obtained with each objective lens is determined by
multiplying the magnication of the eyepiece times the magnication of the objective. Keep
in mind that as magnication increases, eld of view (area of the specimen seen when looking
through microscope) decreases.
• MECHANICAL STAGE: Permits precise, mechanical manipulation of the specimen slide.
• MECHANICAL TUBE LENGTH: Distance between the top of eyepiece tube to mounting face of
nosepiece. (On more advanced models, above elementary type, the tube length is 160mm).
• NEUTRAL DENSITY FILTER: Neutral colored frosted lter designed to soften illumination hot
spots.
• NUMERICAL APERTURE (NA): Mathematical formula devised by Ernst Abbe for the direct
comparison of objective lens to resolving power.
• NOSEPIECE (REVOLVING TURRET): Designed to hold objective lenses permitting changes of
magnication by rotating different powered objective lenses into optical path. Forward facing
position used on elementary and high school models. Reverse facing nosepiece position used on
more advanced models permits easier access to stage when positioning specimen slides.
• OBJECTIVE LENS: Lens closest to the object being viewed, forms rst image of the specimen.
• OIL IMMERSION LENS: High power (100x) objective lens which requires a medium of immersion
oil between the lens and the slide
• RESOLVING POWER: Ability of the optical system to distinguish and separate ne structural
details in a specimen. The resolving power is limited by the NA of the objective, and it also
depends upon the working NA of the sub-stage condenser, the higher the effective NA of the
system the greater will be the resolving power.
• RHEOSTAT: Variable potentiometer that adjusts the light intensity of the illuminator.
• SEIDENTOPF BINOCULAR HEAD: Seidentopf heads remain parfocality when changing
interpupillary distances and are supplied with one adjustable diopter adjustment to adjust image
for any difference in vision between left and right eyes.
• SPECIMEN SLIDE: Typically a 3 by 1 inch by 1mm thick glass with a specimen held for
observation covered by a .01mm thick cover glass.
• STAGE CLIPS: Two locked-on clips hold specimen slide in place on stage.
• STAGE: Platform of the microscope where the specimen slide is placed.
• SAFETY RACK STOP: Prevents higher power objectives from breaking specimen slides, and
prevents damage to objective lens. Stop has been pre-adjusted at the factory.
• TENSION ADJUSTMENT COLLAR: The tension collar is used to adjust and control “body tube”
or “stage” drift (Instrument not remaining in focus).
• TRANSMITTED ILLUMINATION: Used to illumination both compound and stereo microscopes
providing illumination from below specimen.
• WORKING DISTANCE: Distance between the top of specimen slide and the front of the objective
lens.

CARE AND MAINTENANCE OF MICROSCOPES
I. WARNING: For your own safety, turn switch off and remove plug from power source before
maintaining your microscope. If the power-cord, AC power converter, recharger, or any of the
supply cords are worn, cut or damaged in any way, have it replaced immediately to avoid shock or
re hazard.
II. OPTICAL MAINTENANCE
A. Do not attempt Do not attempt to disassemble any lens components. Consult a microscope
service technician when any repairs not covered by instructions are needed. Prior to cleaning
any lens surface, brush dust or dirt off lens surfaces using a camel hair- brush. Or use air to
blow dust and lint off surfaces. Use of compressed air in a can, available at any computer
supply store, is a good source of clean air.
B. Do not remove eyepieces or objective lenses to clean. Clean only the outer lens surface.
Breath on lens to dampen surface, then wipe with lens paper or tissue or use a cotton swab
moistened with distilled water. Wipe lenses with a circular motion, applying as little pressure
as possible. Avoid wiping dry lens surface as lenses are scratched easily. If excessive dirt
or grease gets on lens surfaces, a small amount of distilled water or Eyeglass lens cleaner
can be used on a lens tissue. To clean objective lenses, do not remove objectives from
microscope. Clean front lens element only, following same procedure. NOTE: Fingerprints or
other matter on the front lens element of the objective lens is the single most common reason
that you will have difculty in focusing the microscope. Before having costly servicing done,
or before returning for “warranty repair”, make certain to examine the front lens element with
a magnifying glass or eye loupe for the presence of such contaminants. If a microscope is
returned for warranty repair, and it is determined that such contaminants are the problem, this
is not covered under warranty and an estimate for cleaning will be submitted for cleaning.
III. MECHANICAL MAINTENANCE
A. Rack Stop (compound microscopes only): Rack stop screw has been pre-adjusted at the
factory and should not require re-adjustment. However, if you do attempt re-adjustment of
rack stop use the following procedure. Locate rack stop as shown on drawing of your particular
model. Loosen locking nut by turning counter clockwise that should allow you to loosen rack
stop screw by rotating counter clockwise.
a. Models with ne focus adjustment require setting it at mid-range, then using coarse focus
knobs focus on standard slide until sharp image is obtained.
B. Rotate rack stop screw in clockwise direction until tight. Lock into position with the locking
nut.
IV. VIEWING BODY OR STAGE DRIFT: Coarse focus tension adjustment collar prevents the viewing
body or stage from drifting down from its own weight and causing the image to move out of focus.
This has been adjusted at the factory, but over the course of time it may require adjustment. It is
recommenced that you leave the tension adjustment as loose as possible for ease of focusing, yet
not so loose that it permits viewing body or stage to drift out of focus on its own weight.
A. Mid range focusing Models S71000A and S71000B do not require adjustments for stage drift.
B. Coarse focus only and coarse focus with ne focus models have a tension adjustment collar
located between arm and coarse focus knob on left side of microscope. Use a small jewelers
screwdriver or use supplied 0.90 “L” hex wrench, loosen the setscrew located in only one of
the four holes on tension adjustment collar. Turn collar clockwise to tighten tension, counter-
clockwise to loosen tension. Use of a wide rubber band will provide a better grip on the tension
adjustment collar. After adjusting, tighten the setscrew to lock collar in place.
C. Coaxial coarse and ne focus models have the tension adjustment knob located between
stand and coarse focus knob of microscope (on right side with arm facing user). Tighten
tension of coarse focus knobs by turning tension adjustment knob in a counter clockwise
direction.

GENERAL INSTRUCTIONS FOR COMPOUND MICROSCOPES
I. Remove microscope, vinyl dustcover and any components from Styrofoam lined carton. Retain
the container, and use it for extended storage, for transporting, or in case the microscope ever
needs to be shipped. Always carry microscope by grasping arm with one hand and placing other
hand under base. Place the microscope directly in front of you in a manner, which permits you
to comfortably look into the eyepiece. On models with a rotating head, note that the head of the
microscope rotates 360°, permitting you to operate the microscope from the front or the back,
whichever is most convenient. Most users will position the microscope with the arm facing you so
that focusing knobs are most convenient to reach.
II. Turn illuminator on in order to illuminate the specimen.
A. Models supplied with a variable rheostat knob or dial for controlling light levels.
B. Before operating microscope, adjust intensity (rheostat) control knob or dial to its minimum
position. (This will help extend the life of the light bulb).
C. Turn illuminator switch to the “on” position.
D. Rotate intensity knob until image is illuminated.
E. As different magnications are selected it will be necessary to adjust the intensity of light to
match requirements of objective and specimen slide.
III. Focusing your compound microscopes.
IV. Rotate coarse focus knobs in a direction that stage moves “away” from the objective lenses as far
as possible.
V. Positioning specimen slide.
A. Stages with standard stage clips. Place specimen slide cover slip facing up, under the two
stage clips located on stage. Move specimen slide until it is centered over lens in center
condenser lens located in middle of stage.
B. Mechanical Stage Models: Swing movable nger on holder outward, place specimen slide
(cover slip facing up) on top of slide against xed side of slide holder. Slowly release movable
nger until it makes contact with specimen slide. Using mechanical X and Y controls move
specimen slide until it is centered over the condenser lens.
VI. Initial diaphragm adjustments.
A. Models with rotating disc diaphragm turn until largest aperture is positioned beneath
condenser lens.
B. Models that are supplied with iris diaphragm, move lever until iris is close to largest opening.
VII. Positioning Objective: Rotate the nosepiece (revolving turret) until the 4x (smallest) objective lens
clicks into position in the optical path. Note that each time you change from one objective lens to
another you should turn the turret until you hear the click, which indicates that the lens is properly
indexed in the optical path.
VIII. While looking through the eyepiece, rotate coarse focusing knobs until specimen comes into
focus. If image does not appear in eld of view, move specimen slide slightly until image appears
in eld of view.
IX. Models equipped with ne focus adjustment knobs, adjust these controls until specimen is in
sharp focus.
X. Adjusting the Diaphragm: Diaphragms are designed to help achieve high resolution of specimen
and provide contrast in the image. Listed below are a few suggested starting points for adjusting
the aperture. Smaller apertures will deliver higher contrast to image. However, closing aperture
too much will reduce resolution. Experimentation is the best method of determining the correct
opening of diaphragm.
A. Disc diaphragm
• 4x diaphragm disc close to smallest opening.
• 10x diaphragm disc at medium opening
• 40X diaphragm disc close to largest opening

15
B. Iris Diaphragm suggested openings:
• 4x objective-iris open 1/8,
• 10xobjective-iris open 1/8 to ¼,
• 40x objective, iris open ¼ to ½,
• 100xobjective-iris open ½ to ¾
XI. Changing magnication is accomplished by rotating by rotating objective turret until different
objective lens is moved into optical path. Always turn turret until you hear the “click”, indicating
that lens is properly indexed. Otherwise, you will not be able to see anything when looking through
the microscope. A slight adjustment of focus and diaphragm openings will be needed to sharpen
the image when changing objective magnication.
A. Models supplied with 100x oil immersion lens. To obtain the maximum resolution of the 100x
oil immersion lens it is necessary to apply immersion oil between cover glass of slide and front
lens of objective. Use a very small amount of immersion oil. Air bubbles must be removed from
between lens and slide by gently moving nosepiece back and forth.
B. Each time immersion oil is used on the 100x it is essential that you clean front of lens after use.

MODEL S71000
To view transparent specimen slides, place slide over the
aperture in the middle of the stage, with the specimen
and cover slip on the slide facing upward. The distance
between the specimen and the bottom of the objective
lens will about 1 inch. Grasping the eyepiece tube, gently
slide it down until the objective lens is fairly close to the
slide surface. Note that there is a small-anged rivet in
the eyepiece tube that will stop the downward movement
of the eyepiece tube before it reaches the slide surface.
Looking through eyepiece, gently pull up on eyepiece tube
until image comes into sharp focus.
To view solid objects such as rocks, plants, insects,
or opaque specimen such as stamps, fabric, etc.: The
focusing procedure is same as described under above.
The only difference is that you will want adequate ambient
light in order to illuminate your opaque specimen from the
top. If the specimen is small and falls through the aperture
at center of stage, place a small piece of paper under
the stage clips on the stage surface. Center the opaque
specimen on the paper. When viewing solid objects,
maximum specimen height is 30mm. Anything taller than
30mm will not come into focus.
