Product description
We can provide single-wavelength or broadband polarization beam splitting prisms. These PBSs are made of glass materials and achieve the polarization effect through dielectric beam splitting films.
After unpolarized light passes through the PBS, the light emerging along the propagation direction is pure P-polarized light, and the S-polarized light is reflected from the side. The transmitted P-polarized light has a good extinction ratio. Depending on the coating, the extinction ratio can range from 300:1 to 10000:1.
Note: Specific wavelength bands and extinction ratios can be customized according to customer requirements.
Characteristics
- Vertical incidence, facilitating optical path adjustment
- Good degree of polarization
- Low price
- The operating band can be either single-wavelength or broadband
- Compact structure
