    • 280 nm Bandpass Filter

    The MP-BPF-280 is a high-performance bandpass filter designed for ultraviolet (UV) spectral applications. It features a center wavelength of 280 nm and a full width at half maximum (FWHM) of 22 nm. Manufactured with advanced hard dielectric coatings, the filter provides excellent transmission in the target band while offering deep blocking of visible light and out-of-band UV wavelengths, effectively improving system signal-to-noise ratio. This filter is suitable for UV fluorescence detection, UV imaging, life science analysis, environmental monitoring, UV laser systems, and other applications, making it a critical optical component in research and industrial instruments.

    Product features：Center wavelength 280 nm；FWHM bandwidth 22 nm；Guaranteed minimum bandwidth 20 nm；Average transmission > 65% in the passband；Hard dielectric coating with excellent environmental durability；High stability and long service life

    Part Number：MP-BPF-280

    Application area：UV fluorescence analysis | Protein detection | UV imaging systems | Environmental monitoring instruments | Research laboratory
