This holder is used to adjust the polarization orientation of the polarizer and the crystal axis of the wavelength plate.
It can be used for precise polarization experiments with a mechanism that can smoothly rotate 360 degrees around the optical axis.
The SPH has a fine tuning mechanism in the rotation mechanism and is used to create a high extinction state by adjusting the polarizer.
The PH and SPH types are equipped with freely movable scale plates that allow easy adjustment of the polarization and crystal axes.
The SPH can rotate the rod mounting direction by 90 degrees, allowing you to perform fine adjustment operations and read tick marks from the side.
The SPH is equipped with a clamp for the fine adjustment mechanism to avoid misoperation after adjustment.
The element is secured to the holder by a screw ring and a resin ring (made of Delrin).
The MPH type can be used in miniaturized optical systems and in narrow spaces to use polarizers.
For PH and SPH types, the device case can be removed and replaced with a polarizing prism adapter.
* For PH and SPH types, when removing the supplied rod and using the M6 screw to secure the holder, make sure that the tip of the screw does not go deeper than 5 mm from the bottom of the holder.
* If you use a long screw, the tip of the screw may interfere with the rotating mechanism and the holder may not rotate smoothly.
