NIR Sensors

Filters for NIR sensors and detectors i.e. used in coffee
machines, production lines and hygeine applications.

NIR Sensors

The application environment

IR detectors and sensors are applied in all kinds of applications and environments. Vending machines, cup detectors in coffee machines, production lines with part detectors, hand dryers, soap and paper dispensers just to name a few.

Typical filter requirements

  • Effective transmission / attenuation the in the desired wavelength range
  • Anti-reflection (AR) coating
  • Optimized anti-reflection (AR) coating
  • Cleaning & chemical resistance
  • Impact resistance
  • Black panel effect
