Polarization element holder

[Features]
· The POH-30, POH-50 hold polarizing plates and wave plates and is used for the adjustment of polarizing surfaces, etc.
· For devices such as Glan-Thompson prisms and wave plates with small external shapes, combine with an adapter for polarizer element holders.
· When the coarse movement clamp is loosened, it can move coarsely over 360°. When the coarse movement clamp is tightened, it can perform fine adjustments on the micrometer head.
· Since the scale ring moves independently, the zero point can be set to any angle.
· The C-301- (1) is a holder for holding cube type prisms. It does not include a tilt adjustment function, etc.
