Used to fix polarization optics, allowing 360°of continuous rotation to achieve adjustment by 2°of scale accuracy；The position of the adjuster and the rotation of the mount can be locked separately with setscrews；Can clamp optics with two sizes, i.e.25.4mm and 50.8mm.
| A standard-size polarization optic is oriented perpendicular to its optical axis； |
| Suitable for polarization optics, wave plates, etc. with a diameter of 25.4mm or 50.8mm； |
| 360° of arbitrary rotation can be achieved in the manual version, and there is a mark every 5° along the outer circle; the cursor sub-scale is designed, with a minimum accuracy to 2°； |
| The threaded rings are used to fix 25.4mm and 50.8mm optic assembly, combined with the use of plastic rings, achieve stable fixing without damage to the polarization optic, wave plate, etc； |
| In the product, there is a threaded ring. |
