March 22, 2019 – San Diego, CA – Gamma Scientific announces the release of its RS-7 Iris Option. An enhancement to the SpectralLED® family of uniform intensity tunable light sources, the stepper-controlled Iris feature provides a variable output aperture which is fully integrated into the light source architecture. Available for both Visible and SWIR output models, the standard RS-7 firmware includes aperture control and additional API commands, allowing easy adjustment of output intensity.  Particularly when used for irradiance test and characterization of bare sensors, the Iris option considerably increases the dynamic range of the light source.

The RS-7 base platform incorporates the latest LED technology available, with the RS-7 VIS series, comprised of 35 discrete wavelength LEDs, delivering a nearly continuous spectrum from 380nm to 1000nm. This allows for an unprecedented color gamut and applications otherwise impossible for traditional halogen or LED light sources. The SpectralLED® SWIR series employs LED’s at 9 discrete wavelengths from 900nm to 1700nm in the Short-Wave Infrared portion of the spectrum, providing a fully programmable spectra with highly uniform and stable output.

The standard configuration incorporates a controller and all software for full spectral calibration with spectral fitting, preset storage and real-time optical feedback in a variety of measurement units. USB drivers for Windows, OSX and Linux platforms are included, and external interface and control can be easily achieved via simple ASCII commands.  Custom configurations are also available.  For more information, please see
