Cylindrical Lens Mount, Adjustable, 50.8 mm Max, +/- 5 Deg., 2 arcs sec

The CYM-2R Adjustable Cylindrical Lens Mount can hold and position cylindrical lenses as large as 2 inches in height. What makes this mount unique is its ability to provide rotation about the geometrical center of the lens. This feature eliminates unwanted translation during rotation of the power axis. 100-TPI screws provide a ±5° roll adjustment range with a sensitivity of 6 arc seconds. With the use of adaptors (sold separately), other sizes of cylindrical optics can also be held and rotated about their centers. Adaptors are available to mount 1/4-in., 1/2-in., 1-in and 19-mm high cylindrical lenses. Each one of these adaptors places the center of the cylindrical lens at the CYM-2R's axis of rotation and has a location pin for quick installation.
