RS-7-940 SWIR Uniform Light Source

For the ultimate in resolution and accuracy,  the SpectralLED® 940-SWIR source incorporates 16 discrete LED devices, all with a center wavelength of 940 nm. The output is directly coupled into a 38mm diameter  homogenizing rod, with a length of 190 mm, having a diffuser optically bonded to the output surface. 

The platform is easily adaptable for automated test systems and production line integration, with integrated optical feedback and temperature control to ensure rock-solid stability and consistent results.
