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. Nomenclature used to describe 

components and controls are identified on opposite page.

UNPACKING

Do not discard styrofoam container or packing materials until you are sure shipment is complete 

and undamaged (retain styrofoam 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, fingerprints or oil. Damage of lens surfaces 

occur when they come in contact with such contaminants, and image quality is reduced.

BEFORE USE

When moving the microscope, use both hands and only lay on flat, even surfaces. Damage will 

occur by holding the stage, focusing knobs or head when moving the microscope. Hold carrying 

handle when moving the microscope.

For safety, make sure the power switch is always turned to the off position “O” before replacing 

the bulb or fuse and wait until both the bulb and bulb holder have cooled down.

Replacement bulb: 2W LED replacement module. Part #HS3-001

SETTING UP THE INSTRUMENT

Avoid placing the instrument in locations exposed to direct sunlight, dust, vibration, high humidity 

and where it is difficult to unplug the power supply cord.

MAINTENANCE

1.  Wipe lenses only with lens paper.

2.  Never disassemble the microscope other than to change the bulb (instructions on page 6). 

Disassembling the microscope will affect performance and void warranty.

3.  Cover microscope with dust cover provided after each use.
