Versatile LED light source for a very broad range of applications
RS-7 Series SpectralLED® Light Sources
The advanced RS-7 SpectralLED® light source offers the finest and most versatile controlled light energy technology available.
This popular multiple award winning SpectralLED® tuneable and fixed wavelength light source range from Gamma Scientific combines the output of many discrete LEDs to produce an output that can be programed to closely match virtually any illuminant source, or the spectrum of any illuminant reflected by a target.
New units include an SWIR model fitted with 9 short-wave infrared LEDs. The wavelengths chosen make it ideal for synthesis of commercially available light sources for calibration and testing of night vision sensors, remote sensing sensors and industrial monitoring equipment. Another model has a fixed wavelength of 940 nm for testing devices used for facial and gesture recognition. A new IRIS option has also been launched which offers a motorised aperture to extend the RS-7's dynamic range.

Offering substantially longer calibrated and stable lifetimes than tungsten sources, the RS-7 series SpectralLED® Tuneable LED Light Sources can sweep through wavelengths to simulate a scanning monochromator, but with the advantage of no moving parts.
In addition to good spectral resolution and accuracy, the SpectralLED® is about 10x brighter than any competitive product. This allows measurements over a much larger, linear dynamic range, and is sufficient to illuminate virtually any detector at levels up to saturation.
The SpectralLED® uses highly stabilised DC drive current circuitry to vary output luminance, rather than pulse width modulation (PWM). This is critical when testing high speed silicon detectors which can easily time resolve PWM signals. Consequently, the RS-7 is ideal for wafer level testing of CCD and CMOS sensors and a turnkey RS-7-4 drop-in model has been developed for existing image sensor testers from manufacturers such as Teradyne and National Instruments. It can also be readily adapted for custom instrumentation built to test head manipulators and handlers.
