800 nm Narrow Bandpass Optical Filter

The MP-NBP-800 is a high-performance narrow bandpass filter designed for applications around 800 nm. Employing a multilayer dielectric interference coating design, it provides high transmission within the operating band of 794-806 nm while offering deep out-band blocking from the visible to the near-infrared. The filter delivers an average in-band transmittance of Tavg > 93% and achieves blocking levels up to OD > 8 in specific spectral regions, effectively suppressing excitation light, stray light, and off-target signals, thereby improving the signal-to-noise ratio and spectral selectivity of optical systems. Supplied in a Ø25 mm mounted format with clearly defined angle-of-incidence and cone-angle specifications, this filter is suitable for precision optical systems that demand high spectral selectivity, out-band rejection, and long-term stability.
