BP880nm NIR Bandpass Filter | CWL 880nm, FWHM 175nm, OD3 Blocking

The BP880nm is a precision near-infrared bandpass filter engineered for reliable spectral control in industrial and scientific optical systems. With a center wavelength of 880 ±5 nm and a 175 ±5 nm passband spanning 800 nm to 960 nm, it delivers over 90% peak transmission while maintaining deep out-of-band blocking of OD greater than 3 across the 200 nm to 1200 nm range. Fabricated with durable hard dielectric thin-film coatings on high-quality optical substrates, this filter delivers consistent performance even in demanding operating environments, making it a trusted choice for OEM integration and prototype development.

Technical Specifications

Applications

This 880nm filter is optimized for a wide range of near-infrared optical applications. It is widely deployed in machine vision systems for barcode scanning, surface defect inspection, and precision position sensing. Additional common uses include laser line conditioning, industrial inspection equipment, analytical instruments, and biomedical imaging setups that require precise NIR wavelength selection. Its high transmission and deep out-of-band blocking properties effectively improve system signal-to-noise ratio and detection accuracy in real-world operating conditions.
