Infrared Narrow Bandpass Filter 825-870nm

The Midwest Optical BN850 is for commonly used IR illumination operating at or around the 850nm wavelengths, BN850 filters feature a narrow band design and is ideal for use when ambient light conditions create poor contrast. Commonly used in security, traffic control, LPR and industrial inspection applications.

Available Models Include:

- Narrow band design for overwhelming ambient light conditions
- Bandwidth 40-50 nm (+/- 10 nm) FWHM
- Available for all commonly used IR illumination wavelengths
- Ideal for security, traffic control and industrial inspection applications
- Suitable for use with laser diodes
- Durable and environmentally stable
- Less sensitive to angle of incidence variations than traditional interference filters
