Overview
The Feasa Infrared LED Analyser is a multichannel instrument for fast, repeatable wavelength and intensity measurement of infrared LEDs in production. Operating across 700–950nm, it's trusted across automotive sensing, security and industrial applications worldwide.
Unlike visible LEDs, infrared devices must be verified using dedicated optical measurement techniques. The Infrared LED Analyser provides accurate wavelength and output measurements, ensuring every device performs as intended.
Supporting multiple channel configurations and a choice of optical fibres, it integrates easily into automated production systems while delivering fast, reliable infrared LED measurements.
