    • 405-488-532-635 nm Multi‑Band Laser Notch Filter

    The MP-MNF-405-488-532-635 is a high‑performance multi-band laser notch filter that simultaneously provides deep blocking at the laser lines near 405 nm, 488 nm, 532 nm, and 635 nm, while maintaining high transmission across other visible and near-infrared wavelengths.This filter is ideal for optical systems that employ multiple laser sources simultaneously. It effectively suppresses excitation lasers, stray light, and background noise, thereby improving the detection contrast and signal-to-noise ratio for fluorescence signals, Raman signals, and other target optical signals. The product is offered in a standard 25 mm round format, available both in a mounted frame and unmounted, facilitating easy integration into microscopy imaging, spectral analysis, biomedical detection, and laser measurement equipment.

    Product features：Simultaneous blocking of laser lines near 405 nm, 488 nm, 532 nm and 635 nm；Laser blocking depth > OD6；Average transmission > 93 % in non‑blocked bands；Covers visible to near‑infrared spectral range；Designed for multi‑laser source systems；Standard 25 mm round size

    Part Number：MP-MNF-405-488-532-635

    Application area：Multi-channel fluorescence microscopy | Confocal laser scanning microscopy | Fluorescence spectroscopy | Raman spectroscopy | Multi-laser analytical instruments
