eyepiece adapters
As
eyepieces of different power have different lengths,
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 90º cross hairs, or upon request a 60º cross
hairs or a single filar cross hair can be substituted. Special
types of reticles can also be supplied. Adapters are
not included with eyepieces, but can be ordered individually if desired.

eyepiece
and objective combinations for the M101A microscope
The M101A has a 160mm 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.
