    • 704 nm Bandpass Filter

    The MP-BPF-704 is a high-performance optical bandpass filter designed for optical systems that require precise spectral selection and efficient stray light suppression. Employing precision thin-film filter technology, it offers excellent transmission in the target band while providing deep blocking of out-of-band spectra. It features good wide-angle incidence adaptability, maintaining stable spectral performance under different incident angles. With a compact structure and steep spectral transition edges, the filter is easy to integrate into various precision optical instruments and is suitable for applications such as spectral imaging, machine vision, industrial inspection, optical sensing, spectral analysis, and research instrumentation.

    Product features：High transmission performance； Wide angle adaptability；High transmission at large angles；Wide blocking range；Stable optical parameters
