GTPC-PH/GTPC-SPH/GTPC-ADP
Compatible Glan-Thompson Prism Part Number
Compatible Optics Diameter
Compatible Optics Thickness
Zoom

Used to adjust polarizing prisms such as Glan-Thompson prisms. Best used for precision alignment of Glan-Thompson prisms or for polarimetry 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.
W4027
◦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.

▶Post length can be changed by specifying the post length when you place an order. We may charge the difference in price depending on the length. Contact our Sales Division for more information.
▶Holders for polarizing prisms of diameters or thickness not in the specifications listed in the catalog can be made to order.

Attention

▶These holders are sold separately from the corresponding optics.
W3450
▶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.

Variable Scale Plate

Zoom

The angle scale position of PH-ARS, SPH-ARS, GTPC-PH and GTPC-SPH can be freely adjusted.
The scale is easily adjusted to the polarizing axis or the crystal axis of a waveplate by changing the position of this scale plate.
This scale plate enables customers to change the scale position during an experiment, or to adjust the scale to the polarizing axis or the crystal axisprecisely. (The default direction is aligned to the vertical axis, within ±1 degree.)

[How to adjust scale plate]
(1) Mount a polarizing optic in the polarizer holder, and set the direction of the polarizing axis and crystal axis to the polarization reference coordinate.
(2) Tighten the clamp screw for rotation, loosen the set bolt that secures the scale plate, and rotate the scale plate.
(3) Set the scale mark to the required scale position, and tighten the scale plate with the set bolt.
Mounting Compatibility of Polarizer Holders and Polarizing Prism Holders

Zoom

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.
