The application environment

Automatic license plate recognition (ALPR / LPR / ANPR) uses optical character recognition on images to read vehicle number plates. The technology is often based on infrared (IR) light, why an IR filter is applied. 

PSC products and solutions

We manufacture NIR transparent acrylic filters which block all visible light completely. We call these filters solutions Solaris™ IR S 306. Our casted acrylic filters combined with anti-reflection (AR) or optimised AR surface treatments result in excellent filter solutions for traffic and speed enforcement cameras. With our optimised AR surface treatment it is possible to obtain extra high performance including enhanced precision and fast recognition.

Typical display window requirements

  • Effective filtering
  • Anti-reflection (AR) coating
  • Optimised anti-reflection (AR) coating
  • A minimum of cleaning
  • Impact resistance
