Mounting Compatibility of Polarizer Holders and Polarizing Prism Holders

Polarizer holders (PH-ARS, SPH-ARS) can be used as polarizing prism holders by purchasing an adapter (GTPC-ADP) additionally. Also, by purchasing the adapter (GTPC-ADP), a polarizing prism holder for either of the three diameter sizes, φ15, φ25.4 or φ30mm, can be used for the other two sizes. However, the adapter is not compatible with the old type prism holders of custom orders (GTPC-PH-＊＊, GTPC-SPH-＊＊).
Adapters (for optic diameter of φ30 and φ50mm) for polarizer holders (PH-ARS) are also available as a single item. Contact our International Sales Division for more information
