1. 0 INTRODUCTION
Congratulations on the purchase of your new ACCU-SCOPE Stereomicroscope. ACCU-SCOPE’S 3055
Stereomicroscope series incorporates the highest quality optical elements to produce high resolution, three-
dimensional images at all magnifications. Versatile, multi-functional and built to withstand years of heavy
use the 3055 Stereomicroscope series is ideal for electronics, industry, research, life science and
educational applications.
2.0 IMPORTANT FEATURES
ACCU-SCOPE’S Stereo microscopes have fixed magnification systems. Total magnification power is the
product of objective magnification multiplied by the eyepiece magnification:
Microscope Eyepieces x Objective = Total Magnification
3055 10x 1x/2x 10x/20x
3056 10x 2x/4x 20x/40x
3057 10x 1x/3x 10x/30x
Inclined eyepiece tubes allow for interpupillary distance of 55mm to 75mm and diopter adjustment of ±5.
Working distance is 76mm. ACCU-SCOPE’S Stereo microscopes feature a three-way illumination system,
which may be used to provide transmitted light, reflected light or a combination of both. Your Stereo
microscope comes completely assembled and ready to use. Simply follow the step-by step operating
procedure outlined in section 5.0 for years of use from your stereomicroscope.
3.0 MAGNIFICATION SYSTEM
Each microscope in the 3055 microscope series has two objectives. The objectives may be changed by
rotating the objective turret around the finger grips. Additional magnification ranges can be obtained
through the use of 15x or 20x eyepieces. Information, product availability and pricing information is
available from your authorized ACCU-SCOPE distributor.
4.0 ILLUMINATION SYSTEM
The 3055 Stereo microscope series is equipped with a built-in, three-way illuminator system. The
illumination system consists of a 12 volt 10 watt halogen bulb for incident light from above and a variable
12 volt 10 watt halogen bulb transmitted light from below. The intensity of either illuminator may be varied
by rotating the intensity dial located on the side of the base.
5.0 OPERATING INSTRUCTIONS
Follow these simple instructions to begin using your stereo microscope:
1. Your stereomicroscope should always be used on a hard, flat and stable surface.
2. Plug the detachable grounded 3-wire line cord into the microscope. Next plug the line cord
into a grounded electrical outlet. A grounded 3-wire line cord is provided.
3. Select the appropriate light switch for the specimen. There are three types of illumination:
-Incident Light (top) - to view opaque specimens.
-Transmitted Light (bottom) - to observe translucent specimens.
-Incident & Transmitted- to develop contrasting conditions on any variety of specimens.
4. Place a specimen on the stage plate area directly below the center of the stereo microscope
body. While looking through the eyepieces with both eyes, slowly adjust the distance between
the eyepiece tubes until you see a complete circle of light at the same time without moving
your head. The eyepiece tubes are inclined at 45 degrees and rotatable 360 degrees to
maximize your viewing comfort.
5. Focus the stereo microscope at the highest power by turning the focus control knob to the
highest magnification power and then use the large focusing knob(s) to bring the specimen in
to focus. Rotate the control knob to the lower power, making focal corrections by rotating the
diopter collar off of the zero setting for proper focus. This will keep the specimen in close
focus at any magnification. A slight turn of the focus knobs may be needed to sharpen the
focus.
6.0 CLEANING THE OPTICS
Do not attempt to disassemble the inclined binocular body or focusing mechanisms. These have been
aligned and sealed for protection against dust, dirt, or other particles by our factory technicians. Only
exposed surfaces should require cleaning. To clean the stereo microscope:

4
1. Blow dust particles from the lens surface with an ear syringe.
2. Using a lens cleaning solution (available from most camera stores) moisten a cotton
swab, cover the swab with lens paper and carefully clean the lenses and eyepieces. This
method may also be used to remove oily smears and fingerprints, which detract from the
image quality. Glass surfaces should be cleaned very carefully and only when necessary.
NOTE: All optical glass surfaces should be cleaned using a circular motion.
7.0 LAMP REPLACEMENT
If lamp replacement is necessary, follow these simple instructions: DANGER!!! Do not attempt to change
the lamp before allowing it to completely cool
7.1 TRANSMITTED (BOTTOM) ILLUMINATION
1. Unplug the electrical cord.
2. Carefully lay the instrument on its back and unscrew the base assembly
3. Remove the old lamp, and insert the new lamp being careful to avoid leaving fingerprints
on the lamp surface.
4. Reattach the base assembly. Do not operate the microscope unless the base is securely
attached.
7.2 INCIDENT (TOP) ILLUMINATION
1. Unplug the electrical cord.
2. Raise the body to the highest position by turning the focusing knob and lay the
microscope back on its arm.
3. Unscrew the illuminator housing.
4. Remove the bulb from the lamp socket in the lamp housing.
5. Insert the new bulb into the lamp socket using care not to leave fingerprints on the bulb.
6. Re-screw the lamp housing, and return the microscope to the upright position.
Replacement Bulb: Catalog No. 3363 for both top and bottom illuminators
