Prism Holders
Prisms and cube beamsplitters need to be openly mounted so that the entrance and exit beams can pass unimpeded. OptoSigma prism holders (aka prism tables) provide a flat surface with either two or three axes of tilt adjustment built in. The prism can be placed on top of the table and secured by means of a spring clamp. Thumbwheels protruding from the side of the table are used to adjust the tilt of the table over a range of 4 degrees. The third axis, when present, is adjusted over a range of 6 degrees by means of a knob protruding from the side. The base of the tables is threaded 8-32 or M4 for inch or metric post mounting. Alternatively, Prism holders can be mounted directly onto a base plate or a stage by using the two clearance holes provided. The tip-tilt adjustment is built in. 2-axis and 3-axis adjustment versions are available. Prism clamps included. Three standard sizes are available. These Prism tables can be post mounted.
