    • 460 nm Narrow Bandpass Optical Filter

    The 460 nm narrow bandpass optical filter is manufactured using a high-performance hard dielectric multilayer coating process. It is specifically designed for blue-band excitation applications, including fluorescence microscopy, flow cytometry, laser detection, biomedical instrumentation, spectral analysis, and precision optical systems. The filter offers high transmittance in the 453-467 nm band while providing efficient rejection outside the passband. It effectively suppresses background stray light, improves system signal-to-noise ratio and detection accuracy, and meets the demanding performance requirements of research and industrial applications.

    Product features：Center wavelength 460 nm；Average passband transmittance >90%；24.4 nm full width at half maximum (FWHM)；Maximum out‑of‑band blocking up to OD5；Hard dielectric coating with excellent environmental durability；High stability and long service life

    Part Number：MP-NBP-460

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