780-2050nm In Line Polarizer

An In-Line Polarizer operating across the broad 780–2050 nm spectrum is a fiber-optic component that converts unpolarized light into a single linear polarization state with a high Polarization Extinction Ratio (PER). It passes light along one designated polarization axis (e.g., slow axis) while blocking light along the orthogonal axis (e.g., fast axis). Because this specific wavelength range spans Near-Infrared (NIR) through Short-Wave Infrared (SWIR), it covers a wide variety of specialized industrial, telecommunication, sensing, and research applications depending on the operating band.
