Modular Infinity Microscope - Tube Lenses and Extension Tubes
Tube lens assemblies are designed to take a collimated beam and focus the light onto cameras using a C-mount camera adapter.
The collimated-light side of the tube lens assembly is terminated in either a male C-60-RING type fitting (Achromat Lens Tubes) or with a female fitting that accepts a C60-RING.
Extension tubes are used to space components in the collimated light region, and accept C60-RING connectors on each end.
