Helical Focusing Mounts: Unifoc Series


Schneider Optics offers the Unifoc 58 and Unifoc 76 helical mounts used for focusing enlarging lenses that do not contain any internal focusing mechanism. They feature a total focus range (Z-axis travel) of 25.7 mm and differ only by their rear mount. The Unifoc 58 has a “male” T2 thread (M42 x 0.75). The Unifoc 76 has a “male” M58 x 0.75 thread.

Each Unifoc model has an internal “female” Leica mounting thread (Ø39 x 26 Gg. 60°), adaptable also to M39 x 1. The final focus setting can be locked by a knurled locking thumb screw and additionally secured by an opposite Allen screw. The helical mounts can be adapted easily with extension tubes and adapters to a wide range of imaging applications.
