概述
- Material: ultraviolet fused quartz
- Separate the S-polarization and P-polarization
- 45° angle incidence
- Suitable for high power
The 45° Polarization Beamsplitter Plate from Dimension-Labs is a polarization beamsplitter in the Polarization Beamsplitter Plate series that is incident at a 45° angle and the reflected light is 90 degrees to the incident light, with an incidence angle of 45° (adjusted to the optimal angle when used).
