Thank you for your purchase of a Richter Optica microscope. The information in this manual is provided to answer most
questions that can arise when operating your microscope and to help you avoid unneccesary maintenance expenses in
the future.
Please carefully read instructions before operating microscope. Nomenclature used to describe components and controls
are identied on opposite page.
UNPACKING
Do not discard styrofoam container or packing materials until you are sure shipment is complete and undamaged (retain
stryrofoam shipping container to store your microscope when it is not in use). Remove all tape and packing material used
to protect microscope during shipment. Make certain lens surfaces do not come in contact with dirt, ngerprints or oil.
Damage of lens surfaces occur when they come in contact with such contaminants, and image clarity is reduced.
ASSEMBLY & ORIENTATION
1. Slide focus holder onto the silver, vertical post on the microscope stand and secure rmly into
place by tightening the large, black focusing screw on the back of the focusing holder.
2. Place the head of the microscope into the circular focusing holder and tighten the two silver
locking screws to secure.
3. Slide eyepieces into to the eyetubes.
4. Install rubber eyeshields over the tops of the eyepieces. These will help block undesired light
reection and position your eyes at the appropriate level above your eyepieces.
5. Models S2-BL and S2-TPD come furnished with a black and white stage plate. Choose which
side to use depending on whichever provides the best contrast for the specimen you are viewing.
Models S2-BLED and S2-TD-LED come furnished with a black and white stage plate, as well as a
frosted glass stage plate. The frosted glass stage plate is used when viewing transparent
specimen slides or for viewing specimens that are thin enough for light to pass through
(insect wings, plant leaves). To switch plates you will need to loosen the stage plate locking screw.
Once plates have been changed, tighten locking screw back into place.
6. Make certain that the main voltage of your microscope corresponds to the voltage in your power
outlet. Only insert the microscope plug if the power outlet matches.
7. Adjust the interpupillary distance between eyepieces to match that of your own eyes. Looking
through the microscope with both eyes, grasp both sides of microscope head and gently push
eyepiece tubes together or pull apart until you see the images blend into one.

8. Turn objective turret until smaller number (lowest magnication) is facing towards you (away
from silver post), making certain that the turret “clicks” into indexed position.
Magnication is determined by multiplying the number on the eyepieces by the number on the
objective turret. For example, if your microscope is equipped with 10x eyepieces and the turret is
positioned so that the 3x is indexed at the front of the microscope, the resulting total
magnication is 30x.
To change magnication, turn the knurled black objective turret 90 degrees until it “clicks” into
position with the other number facing towards you. Your microscope is parfocalled, and should
need little to no adjustment of the focusing knobs when changing from one magnication the
the other.
9. Place the object to be viewed on the center of the stage plate.
10. With the objective turret placed at 1x, turn the focusing knobs until object being viewed is in
focus.
11. Looking through the right side of the microscope with your right eye, adjust image sharpness by
turning the focusing knobs.
12. Looking through the left eyepiece of the microscope with your left eye, turn the knurled diopter
adjustment collar until the left image is sharp.
You have now adjusted the microscope for your personal vision. When viewing other objects of
various sizes, you should not have to make further adjustment of the diopter, and will only need
to adjust the focus knobs. If other users change the diopter setting for their vision, you will need
to re-adjust your diopter settings.
13. For optimum sharpness of your image in the entire eld of view, it is important to position your
eyes at the correct point above the eyepieces. Looking through both eyepieces, slowly move your
eyes towards the eyepieces to a level where clarity of the entire eld of view is achieved. After a
brief period of viewing, you will easily nd the best point for your vision.
MAINTENANCE
WARNING: For your own safety, turn any switches o and remove plug from power source before
maintaining your microscope. If a power cord is worn, cut or damaged in any way, have it replaced
immediately to avoid shock or re hazard.
1. Optical Maintenance
a. Do not attempt to disassemble any lens components. Consult a microscope service
technician when any repairs not covered by instructions are needed.

3
b. Prior to cleaning any lens surface, brush dust or lint o lens surface using a camel hair
brush. You can also use an ear syringe or canned compressed air, such as that sold by most
computer stores.
c. To clean eyepiece lenses, do not remove from eyepiece tube. Clean only the outer lens
surface. Breathe 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 windex can be used on
a cotton swab or lens tissue. To clean objective lenses, do not remove objectives from
microscope. Clean front lens element only, follow same procedure.
TROUBLESHOOTING
Light Fails to Operate (LED
STANDS ONLY)
Unable to focus image
Poor resolution
(image not sharp)
Spots in eld of view
Light switch in “o” position
LED bulb burned out
Objective turret not positioned
correctly.
Focusing holder is positioned
either too high or too low on the
silver post.
Objective lenses dirty
Eyepiece lenses dirty
Eyepiece lens dirty
Turn light switch to “on”position
Consult Microscope technician to
properly replace LED bulb
Turn objective turret until it “clicks”
into the index position.
With one hand supporting microscope
head, loosen the locking screw on the
back of the focus holder and reposition
until object comes into focus.

Problem Reason for Problem Solution
***Spots in eld of view can also result from dirt on inside of eyepiece. It is recommended that you have a
service techician clean the inside of your lenses.
