IRIS is the new option for Gamma Scientific’s RS-7 LED Light Sources

Gamma Scientific has just announced the release of their RS‐7 IRIS option that allows easy adjustment of the light source’s output intensity.

This new enhancement for the SpectralLED® family of uniform intensity tunable light sources considerably increases the dynamic range of the light source. It is particularly useful for irradiance testing and characterisation of bare sensors.

The stepper motor controlled iris provides a variable output aperture which is fully integrated into the light source architecture. Available for both the visible and SWIR output models, the standard RS‐7 firmware includes aperture control and additional API commands.

About the SpectralLED®

The RS‐7 base platform incorporates the latest LED technology available. The RS‐7 VIS series contains 35 discrete wavelength LEDs, delivering a nearly continuous spectrum from 380 to 1000 nm. This allows for an unprecedented colour gamut and applications otherwise impossible for traditional halogen or LED light sources.

The SpectralLED® SWIR series employs LEDs at 9 discrete wavelengths from 900 to 1700 nm 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 contact us or visit: https://www.elliotscientific.com/Gamma-Scientific-Light-Sources

 

 


RS-7 SpectralLED® Tuneable LED Light Source brochure updated

The multiple award winning SpectralLED® tuneable visible light sources from Gamma Scientific combine the output of nearly three dozen discrete LEDs – each having a different centre wavelength – to produce output that can be programmed to closely match virtually any illuminant source or the spectrum of any illuminant reflected by a target.

The RS-7-SWIR model is fitted with nine short-wave infrared wavelengths for synthesis of commercially available light sources, making it well-suited for calibration and testing of night vision sensors, remote sensing sensors and industrial monitoring equipment.

New tuneable NIR LED source from Gamma Scientific

A new near infra-red tuneable light source has been developed by Gamma Scientific from their existing digitally programmable SpectralLED RS-7 LED system.

The RS-7-SWIR incorporates 9 shortwave infrared wavelengths for synthesis of commercially available light sources or a spectra of your own design.

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.

Gamma Scientific’s tunable LED light source in webinar demo on September 12th

Gamma Scientifics' RS-7 SpectralLEd light sourceGamma Scientific, in conjunction with Laser Focus World magazine, are delivering an exciting Webinar presentation on Tuesday, September 12th that will provide in-depth product information, typical applications, and visual demonstrations of the flexible software and production interface capabilities that give the RS-7 SpectralLED™ Tunable LED Light Source so many advantages over traditional halogen and other LED light sources.

Register for the Webinar here.

The RS-7 SpectralLED™ delivers superior spectral resolution and accuracy with higher brightness and a broader colour gamut than any other currently available halogen or LED-based source for camera and image sensor calibration.

The RS-7 features 35 discrete LED channels, each having 16-bit resolution in intensity settings enabling it to be programmed to produce a uniform output that closely matches virtually any illuminant source in a single compact and versatile instrument.

SpectralLED™ can sweep through wavelengths to simulate a scanning monochromator, but with the advantage of no moving parts. In addition to superior spectral resolution and accuracy, the SpectralLED™ also offers about 10x higher brightness 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.

Image sensor tests to benefit from new drop-in tuneable LED source

A new turnkey, drop-in calibrated light source for custom and commercially available wafer level testing of CCD and CMOS sensors has been developed by Gamma Scientific from their existing digitally programmable, colour tuneable, RS-7 LED light source.

The new RS-7-4 can deliver virtually any arbitrary spectral power distribution of visible light over a wide range of output luminance. This makes it ideal for accurately characterising a detector’s dynamic range, uniformity, linearity and spectral responsivity.

The RS-7-4 outperforms rival systems due to highly stable DC drive current circuitry that varies the output luminance of manifold discrete LED channels, rather than using pulse width modulation (PWM). This is critical when testing high speed silicon detectors, which can easily time resolve PWM signals and thus give measurement errors.
