Precise rotation about the optical axis for polarizers and waveplates. Polarizer Rotator This mount is suitable for sheet polarizers. It can be rotated and locked at the desired position. A 360° scale provides useful orientation. | Adjustment: | 360 degree | | Resolution through circular scale: | 1 degree for APM-C-50 & 2 degree for APM-C-25. | | | Optics held by threaded ring inside a threaded bore of the device. | | Mounting: | The device can be post mounted. M6 tapped hole is provided at the base for mounting to standard posts. |
| Model No: | Optic Size (mm) | Resolution | APM - C - 25 | 25 | 2 degrees | APM - C - 50 | 50 | 1 degree |

Note: Accessories like post, post holders, post base etc. used for fixing the mount on the breadbord should be purchased separately. Precision Polarizer Mounts Precision rotary adjustments are possible with this mount. Plate/sheet polarisers are held between two threaded rings inside a threaded bore. For other shapes, adapters have to be used. | Fine adjustment range: | +/- 4 degree | | Fine adjustment drive: | By micrometer heads / by 80 tpi leadscrews | | Sensitivity: | 20 arc sec. | | Resolution through circular scale & vernier: | 0.1 degree for APM-P-50 & 0.2 degree for AM-P-25. | | Mounting: | The device can be post mounted. M6 tapped hole is provided at the base for post mounting. | | Construction: | Aluminium alloy | | Finish: | Black anodized |
