Lens Filters

MidOpt Polarising Filters

Polarisers are designed to reduce specular glare by passing only the light polarised in the direction perpendicular to the reflected light (glare). In addition, they help improve contrast, increase colour saturation and detect imperfections in transparent materials. MidOpt Polarising Filters can be easily and securely mounted to your lens and light source for maximum extinction or glare reduction.

Polarising Filters

  • Contrast ratios average up to 10,000:1
  • Linear, circular and wire grid polarisers are available for visible (VIS) and near-infrared (NIR) spectrums
  • Rotating mount with locking thumb screw to fine tune glare reduction
  • Exceptional surface quality; 40/20 scratch/dig

Polarising Film

  • Achieves optimal glare reduction when placed over light source
  • Contrast ratios average up to 10,000:1
  • Linear polarisers are available for VIS and NIR requirements
  • Left and right circular polarisers are available for VIS spectrum applications
  • Offered in high-temperature-resistant laminate and glass
  • PSA007 and HTA008 material comes standard with self-adhesive backing

Polarisers are commonly used to reduce glare from non-metallic in objects with smooth surfaces or surfaces covered with grease, oil or liquid. For best results, use an optical-grade Polariser over the lens and Polarising Film over the light source. The PR120/PG120 offers ultra-high contrast and an anti-reflection oleophobic coating.
