    • 700 nm Bandpass Filter

    The 700 nm high-performance bandpass filter is primarily designed for efficient selective transmission of the target wavelength band while providing deep blocking of out-of-band spectra on both sides of the transmission band. The filter features high transmittance, narrowband spectral selectivity, high out-of-band cut-off depth, and excellent optical stability, effectively reducing the influence of background light and stray light on detected signals. Its circular mounted configuration facilitates integration into imaging, detection, and spectroscopy systems. With optical durability verified through prolonged high-power xenon arc lamp exposure, it is suitable for applications such as fluorescence detection, spectral imaging, machine vision, biomedical optics, and research analysis instruments.

    Product features：700 nm narrowband selection；High transmission performance；Up to OD8 blocking design；Wide blocking range；Narrowband spectral performance；Long lifetime and high environmental stability

    Part Number：MP-BPF-700
