    • 567 nm Narrow Bandpass Optical Filter

    The 567 nm narrow bandpass optical filter is manufactured using a high-performance hard dielectric multilayer coating process. It is specifically designed for yellow-green band excitation and detection applications, and is widely used in fluorescence microscopy, confocal microscopy, flow cytometry, biomedical detection, Raman spectroscopy, and precision optical instrumentation. The filter offers exceptionally high transmittance in the 559.5-574.5 nm band while providing broad-spectrum, high-rejection performance outside the passband. It effectively suppresses excitation light leakage and background stray light, improves detection sensitivity and imaging contrast, and meets the demanding requirements of research and industrial applications.

    Product features：Center wavelength 567 nm；Average passband transmittance >95%；22.7 nm full width at half maximum (FWHM)；Multi‑band high‑blocking design, maximum blocking up to OD5；Hard dielectric coating with excellent environmental durability；High stability and long service life

    Part Number：MP-NBP-567

    Application area：Fluorescence microscopes | Confocal microscopes | Photoelectric sensors | Spectral analysis instruments | Research and laboratory equipment
