MidOpt BP Series Filter BP540

Uniforce Product

Salient Features

BP540 (Limited Availability)

BP540 filter material is designed for use with green LED lighting. 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.

Threaded Mount Technical Drawing PDF

Slip Mount

  • Designed for varifocal lenses, wide angle lenses and lenses without filter threads
  • Accommodates standard threaded mounts
  • Low profile and oversize diameter design prevents wide angle lens vignetting
  • Locking set screws and a wrench are provided to secure the adapter to the lens
  • Many varifocal and shorter fixed focal length (wide angle) lenses are not supplied with filter threads due to the presence of a protruding, strongly convex lens element. Our slip mount adapters allow standard threaded filters to be fitted securely to these and a large variety of lenses that do not have filter threads provided.

Ordering Example:

  • Filter: BP470
  • Outside Diameter of Lens in mm: 43mm

Correct Part# is:

  • BP470-S43

C/CS Camera Mount

midopt-c-mount

  • Designed to thread directly into any C/CS mount camera between the lens and sensor
  • Wrenching slots aid in threading the filter into the camera body. A wrench is supplied with each filter.
  • Helpful in applications with space constraints
  • Can be used with wide angle lenses that do not accept filters at the front end to prevent vignetting
  • C/CS mount filters are available in a standard 1mm thickness

Ordering Example:

  • Filter: BP470
  • Mount Size: 25.4

Correct Part# is:

  • BP470-25.4
