Polarizing Bandpass Filters |
|
 |
|
| Highly efficient polarizer and a bandpass filter in a single optical component − only Semrock has it! |
|

These unique, patent-pending filters are superb linear polarizers with a contrast ratio exceeding 1,000,000-to-1. In addition, with high-performance bandpass characteristics (including high transmission and steep edges), they make an excellent laser source clean-up filter (eliminating undesired polarization and light noise away from the laser wavelength) as well as detection filters to pass a laser wavelength range and block background noise.

They are ideal for a wide variety of laboratory laser applications, especially those involving holographic and interferometric systems, as well as fluorescence polarization assays and imaging, second harmonic-generation imaging, polarization diversity detection in communications and range finding, and laser materials processing.

Key product highlights include:
- Contrast ratio > 1,000,000:1
- High transmission (> 95%) within optimized passband (for p-polarization light)
- Imaging optical quality – low scatter, wavefront distortion, and beam deviation
- Hard-coating reliability and high laser damage threshold (1 J/cm2)
- Large clear aperture coupled with 90° beamsplitter functionality
- Excellent out-of-band blocking

Polarizing Bandpass Filters – These filters come in a rectangular format with dimensions of 25.2 mm x 35.6 mm x 2.0 mm thick. Semrock's custom-fabricated Beamsplitter Mount is ideal for holding these for laboratory bench-top setups.
When ordering a part mounted in Beamsplitter Mount, please specify if you are using the filter as a polarizer or an analyzer for proper orientation during assembly.
