TECHSPEC® C, S, and T-Mount Polarizer Holders are used to easily integrate polarizers or retarders into C, S, or T-Mount optical systems. The holders are designed to allow the polarizer to rotate 90° while the main body of the holder remains in place. Smooth rotation provided by the attached lever allows for the user to easily control the orientation of the polarization axis within the system. TECHSPEC C, S, and T-Mount Polarizer Holders can hold 12.5, 20, 25, or 50mm diameter polarizers between 1.5mm and 9.0mm thick. Use adapters #12-836 or #12-837 for mounting 12.5mm square or 25mm square polarizers, respectively. These holders are ideal for quickly and effectively adding polarization to C, S, or T-Mount systems.
Note: The female portion of the holder must be removed when installing 12.5, 25, or 50mm polarizers using an Allen Wrench. For #90-621, the retaining ring must be removed using a spanner wrench to mount a 20mm polarizer.
