Polarizer Holders (None adapter) / GTPC-PH_GTPC-SPH

Used to adjust polarizing prisms such as Glan-Thompson prisms. Best used for precision alignment of Glan-Thompson prisms or for polarimetery devices.

The fine adjustment mechanism in the SPH can be used to detect an extinction ratio of 10−5 or less.
The scale plate on the PH and SPH series can be positioned to provide a convenient reference to the polarizing axis.
The SPH can be post mounted with the micrometer at the top or at the side for convenient operation in a variety or environments.
The SPH includes a locking mechanism to prevent accidental adjustments.
Polarizing prisms are held in place with retaining rings.
Rotary holders and adapters (GTPC-ADP) are also sold separately.Purchase the combination of three items, a Glan-Thompson prism, adapter and rotary holder, by checking the combinations listed in the following specification table.
