概述
- Material: K9 glass
- Extinction ratio: Tp/Ts: >1000:1, Rs/Rp>200:1
- High extinction ratio requirements, high wavefront distortion (both reflected and transmitted light paths are satisfied)
- Selectable wavelengths: 532nm, 633nm, 780nm, 1064nm, support customization;
- Optional size: 25.4*25.4*25.4mm, 12.7*12.7*12.7mm, support customization;
Ordinary polarization beamsplitter prism (PBS) has a relatively poor extinction ratio for the reflection channel, and is not suitable for applications with extinction ratio for the reflection channel, such as interferometers. Dimension-Labs has optimized the design of the polarization beamsplitter prism to meet the requirements of high extinction ratio and high wavefront distortion for both the reflected and transmitted light paths, and is mainly used in polarization interferometers.
Dimension-Labs offers a wide range of high-performance dual-channel polarizing beamsplitter prisms (specific types and parameters can be filtered in the details below) to meet your needs for a wide range of applications.
