Salient Features

Bi Series Narrow Interference Bandwidth

- 20-35nm FWHM; Narrow bandwidth
- High transmission ≥85%
- Designed for use with laser diodes
- Ideal wavelength separation when multiple light sources of similar wavelengths are present
- Reflective, mirror-type surface that helps minimize thermal effects
- Available in sizes up to 79.5mm sq.

APPLICATIONS: Bi Series are popular for life science and laser analysis applications where only discrete wavelengths need to be passed to maximize system performance.

The Bi832 These filters are available for use in conjunction with commonly used IR LED or laser diode illuminators operating at or very close to the 830nm wavelength. Our new Bi832 filters feature a much narrower band design that is ideal for use when ambient light conditions might otherwise create unacceptable contrast. They can be useful in night vision, security, traffic control, LPR and industrial inspection applications.

Useful Range : 822-846nm
FWHM : 40nm
Tolerance : +/- 5nm
Peak Transmission : ≥90%
Surface Quality : 40/20
Compatible LED : 840nm | Laser: 830nm
Thickness : 1mm

MidOpt StablEDGE™ optical filters are specifically designed to be less susceptible to effects from angular shifting seen when optical filters are placed in front of short focal length (<12 mm) camera lenses.
StablEDGE™ filters take advantage of absorptive filter glass to form the leading
edge of the filter passband.This assures no shifting in this region, even when the
lens FOV exceeds 100°.StablEDGE™ designs are less angle-of-incidence sensitive, inherently more rugged, and are environmentally stable.
