Modular Microscope M101B

The M101B modular microscope includes the M242 10X eyepiece, M250-242 eyepiece adapter, and the M222 objective as standard components. Our Model M101A is identical to M101B shown above but with rack and pinion focusing instead of a focusing sleeve. The standard components can be substituted for components listed below or from others shown on our website. 

eyepiece adapters
Eyepieces of different power have different lengths so the reticle location inside the adapter is different in each adapter permitting the eyepiece to focus on the crosshair reticle. The optical tube length of the microscope will increase a few millimeters for the 14X eyepiece but the overall length of the microscope will remain the same. Each standard adapter contains 90º fiber cross hairs. Adapters when ordered individually do not include eyepiece.

 eyepiece and objective combinations for the M101A and M101B microscope
The M101A and M101B has a 168mm optical tube length with the standard 10X eyepiece. The M193 Erecting Prism adds 26mm to the optical tube length, thereby increasing the magnification and decreasing the field of view and working distance.
