basic modular microscope M101B components diagram

The M101B modular microscope includes the M242 10X eyepiece, M250-242 eyepiece adapter, and the M222 objective as standard components. These components can be substituted for the components listed below or from others shown on our website. 

eyepiece adapters
Eyepieces of different power have different lengths so the appropriate adapter must be used with each in order to permit interchange of eyepieces without altering the optical tube length of the microscope. Each standard adapter contains 90 cross hairs, or upon request a 60 cross hairs or a single filar cross hair can be substituted. Special types of reticles can also be supplied. Adapters when ordered individually do not include eyepieces.

eyepiece and objective combinations for the M101B microscope
The M101B has a 168mm optical tube length. The M193 Erecting Prism adds 26mm to the optical tube length, thereby increasing the magnification and decreasing the field of view and working distance.
