Semrock Polarization filters combine a highly efficient polarizer and a bandpass filter in a single optical component. These excellent linear polarizers have a contrast ratio exceeding 1,000,000 to 1. Because of their high-performance bandpass characteristics, they make excellent laser clean-up filters as well as detection filters.


Note on spectral plots:
In the past, each shipment has included a spectral plot for every filter and every lot code in the shipment. In an effort to be more eco-friendly, we will no longer be including these plots with each shipment. If you require spetral plot data, please see here for more information.
