IR CUT FILTERS

FOR ACCURATE COLOUR REPLICATION IN

PHOTOGRAPHY, CCD AND CMOS IMAGING APPLICATIONS

IR-cut filters are designed to block the NIR spectrum by means of reflection whilst still transmitting in the visible range. Our IR filters are also able to block UV light below 350nm.

Today’s modern camera systems are highly sensitive to infrared light up to around 1000nm causing inaccurate colouration. By fitting an IR-cut filter, unwanted infrared light is reflected away from the detector and true to life colour is maintained.

BOROSILICATE

Knight Optical’s IR cut filters are hot mirror coated on a quality borosilicate substrate which offers sharp transitions between the transmitting and reflecting bands to improve accuracy and control.

Borosilicate will not degrade under normal conditions. The substrate has a low thermal expansion meaning the optic can survive rapid changes in temperature while maintaining its structural integrity where other materials might crack or shatter.

Knight Optical can supply IR cut filters in diameter or square types:

  • 5mm
  • 10mm
  • 12.5mm
  • 15mm
  • 25mm
  • 50mm

We are also able to cut and edge filters for non standard sizes to your specification.
