    • 808 nm Laser Line Filter

    The 808 nm Laser Line Filter is specifically designed for 808 nm laser systems. It efficiently transmits the 808 nm laser wavelength while providing high blocking for adjacent spectral bands. Manufactured with high-precision ion-beam sputtering (IBS) multilayer dielectric coatings, this filter features narrow bandwidth, high transmission, deep blocking, and excellent environmental stability. It is widely used in Raman spectroscopy, laser spectral analysis, fluorescence excitation, biomedical detection, and research instrumentation.

    Product features：Specifically designed for 808 nm laser systems；High transmission at the center wavelength (> 90%)；Ultra‑narrow bandwidth design (3.1 nm)；High selectivity for the laser line；High‑stability dielectric coatings；Suitable for both research and industrial precision optical systems

    Part Number：MP-LLF-808

    Application area：Raman spectroscopy excitation systems | Laser spectral analysis | Biomedical Detection | Semiconductor inspection equipment | Research and laboratory equipment
