Gadgets Manual

Mount a specimen and set your correct interpupillary distance. At the same time, check any areas suggesting a need for mechanical and/or optical maintenance.
Clean any visible dirt spots with alcohol. Do not use ether/alcohol mixture, which can cause damage. Polish all plastic components with soft gauze. Softly brush clean all mechanical parts of the microscope.
Clean all exposed optics.
Do a final check of the microscope image, by observing a specimen.
Remove the stage and condenser (and also, on the B-Max 50, the revolving nosepiece) from the microscope stand.
Replace all removed units onto the microscope stand
Reset the interpupillary distance to its original condition.

Microscope components get dirty with time. Dirt and dust particles on the optical components are especially damaging to image quality. When photographing important specimens which cannot be rephotographed, visible dust particles on the picture can be most frustrating. Therefore, we suggest the following critical microscope components be kept clean and dust-free.
Photoeyepiece
Remove and clean, since dust particles will be focused on the film plane.
Video Camera
Wipe dust particles appearing on the monitor screen. If the particles move only when the specimen or condenser is moved, clean the specimen and/or condenser. If the particle does not move when the CCTV camera is rotated, clean the camera chip.
Eyepieces
Eyepieces get dirty frequently. Wipe carefully and gently so as not to damage the lens coating.
Objectives
Dirt and dust particles directly affect the microscope image. Wipe thoroughly and carefully with a cotton swab.
Condenser
Dirt and dust particles are easily seen. Always dust and wipe clean.
