MidOpt BP Series Filter BP1550

Uniforce Product

Salient Features

Bandpass Filters are used in a variety of industries, including machine vision,factory automation, security and surveillance, license plate recognition, medical and life science, agricultural inspection, aerial imaging, motion analysis, photography and cinematography.

BP Series Broad Bandwidth

  • Designed with a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths
  • Test the effects of monochromatic illumination
  • High transmission ≥90%*
  • Superior out-of-band blocking
  • StablEDGE® design reduces angular dependency and minimizes short-shifting effects
  • Double-side polished glass for exceptional parallelism and optical flatness
  • Available in sizes up to 165mm sq.

APPLICATIONS: BP Series are the most popular filters used in machine vision and factory automation systems and are a critical element in fluorescence imaging.

BP1550 Transmission Data





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.
