    • 786 nm Narrow Bandpass Optical Filter

    The 786 nm narrow bandpass optical filter is a high-performance narrowband interference filter with a center wavelength of 786 nm, featuring high transmittance, broad out-of-band blocking, and excellent spectral selectivity. Manufactured using high-precision multi-layer dielectric coating technology, it effectively suppresses out-of-band stray light and improves the signal-to-noise ratio in the target wavelength band. It is widely used in Raman spectroscopy, fluorescence detection, biomedical imaging, laser systems, spectral analysis, and precision optical instruments.

    Product features：Center wavelength: 786 nm；Average passband transmittance: >93%；Full width at half maximum (FWHM): 29.9 nm；Efficient out‑of‑band blocking (OD5 and above)；Hard dielectric coating with excellent environmental durability；High stability and long service life

    Part Number：MP‑NBP‑786

    Application area：Raman spectroscopy systems | Fluorescence detection systems | Laser systems | Spectral analysis instruments | Scientific research and experimental equipment
