Portable spectroradiometers from Gamma Scientific updated

Gamma Scientific’s new GS-1160 handheld spectroradiometers are stand-alone instruments designed for lighting installers, designers and engineers who require accurate, low cost spectral measurements such as:

  • Colour & Chromaticity
  • Gamma & White balance
  • Flicker & Uniformity
  • Luminance, CRI & Delta UV
  • Spectral power distribution
  • Peak & Dominant wavelength
  • Excitation purity

The Gamma Scientific handheld GS-1160 uses a CMOS linear image sensor, covering the wavelength range from 380 to 780 nm in 1 nm steps.

The instrument offers integration times from under 0.0001 to 5 seconds and delivers the spectral data via an onboard colour graphical display. This data can also be stored on an SD card, making it ideal for the portable spectral evaluation of LEDs, OLEDs and Quantum Dot displays.

The GS-1160B is the desktop version of the above. It features all the same measurement functions, but no display, and outputs the captured data via USB or RS-232 to a PC.

Gamma Scientific unveils newest GS-1290 NVIS Spectroradiometers

The latest version of Gamma Scientific‘s GS-1290-NVIS is an advanced, high-speed spectroradiometer that combines the leading-edge sensitivity of a cooled backside-thinned CCD detector technology with the industry-renowned RadOMA opto-electrical platform.

The GS-1290-NVIS is specifically configured for ANVIS testing of cockpit displays and lighting. It far exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009. The MIL-SPEC requires a 10:1 signal-to-noise (SNR) measurement ratio, whereas the GS-1290-NVIS spectroradiometer is built to deliver an SNR of 100:1 or greater.

The GS-1290-NVIS offers superior sensitivity, an outstanding signal-to-noise ratio, exceptional accuracy, and high-resolution bandwidth coverage. Please contact us for further information.

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.

Display colour, intensity and flicker measured with new instruments from Gamma Scientific

Gamma Scientific [ @gammascientific ] has just introduced two new instruments for display measurements. Both offer colour, intensity and flicker testing of all types of LED, LCD, OLED and Quantum Dot screens.

The GS-1160 is the touchscreen-equipped handheld version, while the GS-1160B is designed for the bench and operates in conjunction with PC-based analysis software. The GS-1160 can also be used as a desktop system as it is supported by the same software.

These spectroradiometers, to give them their proper name, deliver faster results with repeatability superior to filter-based instruments. Additional measurement capabilities include gamma, white balance and uniformity.

Data is output on both via USB, or can also be stored on an SD card in the GS-1160 portable model. The GS-1160B can be programmed for custom testing as it has an Application Programming Interface (API). Commands can be sent via RS-232 or the USB.

For detailed specifications and more information about these or other products Gamma Scientific manufacture, please contact us.

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.
