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

ANPR/ALPR & modern camera systems are highly sensitive to infrared light up to around 1000nm that can cause inaccurate colouration. By fitting an IR-cut filter, unwanted infrared light is reflected away from the detector and true to life colour is maintained. Our IR-cut filters are hot mirror coated on a quality borosilicate or equivalent glass substrate and offer sharp transitions between the transmitting and reflecting bands to improve accuracy and control over the system. The substrate is chemically resistant to acidic and saline solutions and will not degrade under normal conditions. A low thermal expansion means the optic can survive rapid changes in temperature while maintaining its structural integrity where other materials might crack or shatter.

These parts are currently offered at a reduced price whilst stocks last.
