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 unnecessary maintenance expenses in
the future.
Please carefully read instructions before operating microscope.
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.
DESCRIPTION OF COMPONENTS
A. EYEPIECE: Lens closest to the eye. Magnies the primary image formed by the objective lens.
Microscope includes 10x (FN 16mm) eyepiece.
B. OBJECTIVE LENS: Lens closest to the specimen, forms the rst magnied image of the specimen.
Microscope includes 4x, 10x, 40x objective lenses.
C. NOSEPIECE: Revolving turret designed to hold objective lenses, permits changes of magnication
by rotating dierent powered objective lenses into the optical path.
D. STAGE CLIPS: Two locked on clips hold specimen slide in place on stage.
E. STAGE: Platform of the microscope where the specimen slide is placed.
F. COARSE-FOCUS KNOB: Located on each side of the arm, raises or lowers the stage to bring the
specimen tage into focus.
G. FINE-FOCUS KNOB: (located just below coarse focusing knobs) permit more precise image
adjustment.
H. LAMP HOUSE ILLUMINATION: Microscope is provided with a built-in LED illuminator.
I. RECHARGER: Microscope includes a power cord / recharger. The microscope can be operated o
the rechargeable batteries or the power cord.

CHANGING MAGNIFICATION:
a. Magnication is changed by rotating the nosepiece until a dierent lens is moved into the
optical path. Always turn the turret until you hear it “click”. This indicates that the lens is
properly positioned.
b. The standard lenses that are provided with your microscope are a wideeld 10x eyepiece,
a wideeld 16x eyepiece, 4x, 10x and 40x objectives. The 40x objective has a special spring
retractable mechanism which retracts slightly when the front of the lens comes in contact
with the specimen slide. See chart below for magnication options.

c. Also note that each objective has a color ring. This allows you to quickly change
magnication by referring to an easily observed color rather than to a number.
d. The microscope has been parfocalled at the factory, which allows the user to easily change
from one magnication to another requiring little or no adjustment of the ne focus
knobs.
e. As you increase the magnication, the eld of view (area of specimen seen through the
microscope) will decrease. That is why it is easier to nd the specic area of interest on the
specimen by starting with the lowest 4x objective lens , before increasing magnication
with the 10x or 40x objective lens.
f. NOTE: Care must be taken when rotating the 40x objective lens into place. This lens has
a spring retractable mechanism which retracts slightly into its housing if the front of the
lens strikes the specimen slide. With ne focus adjustment at mid-range, the rack stop has
been adjusted at the factory to assure the 40x lens will clear the thickness of a normal
specimen slide and cover slip. However, if the rack stop has been improperly adjusted, or
if you are using a thicker than 0.17mm cover slip, moving the 40x lens too quickly could
cause damage to the front lens element or to the slide.

WORKING CONDITIONS:
This microscope is a precision optical instrument. Follow the guidelines below for optimal use and care.
Keep the microscope out of prolonged direct sunlight.
Working temperature should be between 32˚ and 100˚F.
Keep the microscope out of dusty environments and cover with a dust cover when not in use or store in a cabinet.
Use the microscope on a at and sturdy work surface.
TECHNICAL SPECIFICATIONS:
Total Magnication = 40x, 100x, 400x
Mechanical tube length = 132mm
Parfocal Distance = 30mm
Monocular inclined viewing head 45˚
Included Eyepiece: WF10x, 16mm
Illumination: LED, Rechargeable
MICROSCOPE OPERATION:
Place the microscope on a stable work surface.
Select the desired eyepiece and slide into the eyetube.
Before rst use, connect the power cord to charge the batteries.
Turn on the microscope and adjust the rheostat control.
Place a specimen slide under the stage clips and rotate the 4x objective lens into
position. Make sure the stage is centered above the light.
When the 4x objective is in focus, move up to the 10x or 40x lens.
Focus by rst adjusting the coarse
focus knob, and then the ne focus
knob.

CARE and MAINTENANCE:
When the microscope is not in use, turn the power switch o. When not charging the microscope, unplug it.
Use a piece of silk or absorbant cotton soaked with microscope cleaning solution to clean the body of the microscope.
Cover the microscope with a dust cover with not in use.
Use a blower or lens tissue to clean the objective lenses.
Clean the microscope surface with a soft cloth and for tough stains use a neutral detergent. Do NOT use solvents such as
alcohol or ether as this may damage the paint on the body of the microscope.
Store the microscope in a cool and dry place to keep mildew from building on the lenses or moving parts.
BULB REPLACEMENT:
Turn o the microscope and unplug it.
Unscrew the 3 rubber feet from the base
to remove the base plate.
Remove the LED lamp and replace it.
Screw the base plate back on with
the rubber feet.
Remove Screws

FOCUSING TENSION ADJUSTMENT:
Included with the microscope is a focus
tension adjustment tool. If the stage starts to
drift (slowly fall) and samples are falling out of
focus, the tension adjusment needs to be
adjusted. Insert the tool into the slot on the
coarse focus knob and rotate.
Turning one direction will tighten the tension
and turning the opposite will loosen the
tension.
If it becomes hard to turn the focus knob,
loosen the tension slightly with the tool.
