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.
Built for infrared. Trusted globally.
Dedicated 700–950 nm infrared testing
Test infrared LED output across the 700–950 nm range for applications where visible-light analysers are not suitable.
Comprehensive output parameters
Outputs include infrared wavelength and relative intensity, giving you the data needed to make pass/fail decisions.
Complete software package
The full Feasa Software Suite is included as standard, with DLL and programming examples for LabVIEW, C, C++, C# and Python.
Built for production integration
USB and RS232 interfaces are standard, with up to 30 analysers daisy chained from a single port.
Proven in production
- Millions of LEDs tested every day using Feasa products
- Worldwide usage on production lines by leading manufacturers
