Optical Filters - Polarisers

Produktnummer: Polariser
BESKRIVELSE

Polarisers are used to analyse or create polarized light. Using a dicroitic polymer sheet base, we can offer a wide range of options including sizes, polarization and light transmission.

Common applications:

  • Contrast enhancement display filters
  • Sunlight readable touch screens
  • Photography
  • Stress analysis of glass and plastics
  • Optical sensors and safety light curtains
  • 3D projection systems
  • Ophthalmology

E.g. (picture 3). Sunlight readability is a big problem with resistive touch screens. The combination of badly index matched air gaps and reflective ITO coating results in a barely readable display.

The addition of a polariser and, in some applications a retarder as well, dramatically improves the contrast ratio of resistive touch screen displays. Typical applications that benefit from this technology are portable equipment, marine on deck displays, outdoor displays, avionics
