    • 360 nm Bandpass Filter

    The 360 nm Bandpass Filter is a high-performance narrowband filter designed for ultraviolet fluorescence detection, life sciences, microscopy imaging, and spectral analysis. Manufactured with precision multi-layer dielectric coatings, it provides high transmission around the 360 nm centre wavelength while offering deep blocking of out-of-band light, effectively suppressing stray light and improving system signal-to-noise ratio and detection accuracy. Its excellent spectral performance, stable environmental reliability, and precise fabrication quality make it suitable for advanced optical systems in research, industrial inspection, and medical devices.

    Product features：Centre wavelength at 360 nm for UV‑band applications；Average transmission > 90 % in the 348–371 nm band for efficient light utilisation；FWHM of 28 nm ensuring good wavelength selectivity；Guaranteed minimum bandwidth of 23 nm for high product consistency；Designed for 0°angle of incidence, compatible with standard optical paths；High‑durability dielectric coatings for long‑term stable performance

    Part Number：MP-BPF-360

    Application area：UV fluorescence microscopy | Fluorescence imaging systems | Biomedical detection | Raman spectrometers | Research and laboratory equipment
