Ultra High Contrast Glass Linear Polarizer Sheet 

The PG120 Ultra High Contrast Glass Linear Polarizer is designed to reduce glare, increase color saturation and improve overall image quality when inspecting highly reflective surfaces in harsh, high temperature environments. This innovative glass polarizer solves the temperature sensitivity issues that are common with standard polarizing film, which typically fails or curls when introduced to high temperatures for a extended period of time. The PG120 is ideal for high-temperature-emitting LEDs and can be custom sized for any light source up to 405 x 635mm.


PG120 Ultra High Contrast Glass Linear Polarizer Sheet 

  • Useful Range : 400-700nm
  • Contrast Ratio : 10,00:1
  • Surface Quality : 80/50


The PG120 is abrasion- and solvent-resistant and has an anti-reflection oleophobic coating to maximize transmission while repelling dirt and oil–making it the perfect polarizer for industrial imaging. It’s easy to clean, reliable and has ultimate glare reduction over the entire visible spectrum.

The best results are achieved when high-quality polarizing film, like the PG120, is used over the light source in conjunction with a polarizing filter over the camera lens. Therefore, we also recommend using PG120’s compatible filter, PR120, which is designed for lenses with and without filter threads and is available in sizes ranging from M22.5-M105.

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


  • 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
