Polarization filter

Overview

Unique semlock, these filters combine high-efficiency polarizers and band-pass filters in a single optical component! These high-performance filters are super linear polarizers with a contrast of more than 1000000 to - 1. In addition, with high-performance band-pass characteristics (including high transmission and steep edge), they make an excellent laser source cleaning filter (eliminating unnecessary polarization and optical noise far away from the laser wavelength) and the detection filter wavelength range and block background noise passing through the laser. Semlock's polarization bandpass filter is an ideal choice for various laboratory laser applications, especially involving holographic and interferometric systems, fluorescence polarization measurement and imaging, second harmonic generation imaging, polarization diversity detection in communication and ranging, laser material processing and laser intensity control.
