Color tuneable high uniformity calibration light source

May 15, 2017 //By Julien Happich
Gamma Scientific has expanded its family of SpectralLED tuneable LED light sources for camera and image sensor calibration with a new system having a substantially larger output port, as well as increased output uniformity.

The SpectralLED RS-7-2 mates up to four LED light source engines together with a 1 meter sphere that includes a 300mm output port (other sphere and port sizes are available, as well). The result is a calibration light source for very large area detectors and large field of view cameras that delivers significantly higher brightness and approximately an order of magnitude higher radiometric stability (<0.1%) and wavelength accuracy (0.25 nm) than any competitive product.

The SpectralLED RS-7-2 uses a light engine consisting of 35 discrete LEDs, each having a different centre wavelength, which can be programed on-demand to reproduce the output of virtually any light source (e.g. blackbody, daylight, fluorescent, LED, CIE illuminants), or the spectrum of any illuminant reflected by a target (such as a Macbeth or X-RITE target). The system can even be swept through wavelengths to simulate a scanning monochromator, but with no moving parts.
