The Beamsplitters / Optics Mount 5BM121T is designed to adjust beamsplitters measuring Ø25.4 mm (1"). Fixing screw with a plastic tip clutches a beamsplitter against stainless steel rests. The aperture has a rest-blade around its edge designed to stop optics inside.
Precision Optical Mounts of Side Control enable to greatly increase thickness of optical elements as it has a convenient access to the adjustment handles.L-shaped flat spring of original design renders the great stability of a mount's platform. The spring performs two functions: work as a usual spring, and eliminate polarizing rotation of the platform. Angular range is ± 2° about each of two orthogonal axes. Precision screws with pitch of 0.25 mm render sensitivity of 10 arcsec. Three M4 tapped holes on the sides of the base and on its back allow a variety of mounting configurations, e.g. horizontal and vertical. Beamsplitters / optics mount is produced from black anodized aluminium. L-shaped spring is produced from high quality stainless spring steel.
