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 hones GS-1290 wavelength accuracy to ±0.2 nm

Gamma Scientific‘s RadOMA™ range of advanced, high-speed spectroradiometers deliver millisecond measurement speeds, exceptional low-light measurement capabilities, and superior blue-light region sensitivity. The latest versions of the GS-1290 are now offering wavelength accuracies down to ±0.2 nm.

Multiple configurations cover a wide spectral range, from the ultraviolet to the near infrared:

1220 Display Measurement System

  • 200 to 890 nm (GS-1290-1)
  • 200 to 1100 nm (GS-1290-2)
  • 360 to 940 nm (GS-1290-3)

RadOMA™ spectroradiometers are ideally suited for testing retroreflected colour, reflectance and transmittance, LED colour and luminance, flat panel displays, and light sources.

The systems are completely modular and interchangeable for easy upgrade or customisation, and can be self-calibrated by the user so they never have to be returned to the factory.

Gamma Scientific detected at Photonex

Photonex 2014Newcomer to the Elliot Scientific stable, Gamma Scientific, drew considerable interest over the two days we exhibited at the Photonex Exhibition and Conference held recently in Coventry. Gamma Scientific President Richard Austin was on hand to demonstrate the systems and explain the differences between radiance and irradiance, and luminance and illuminance among other things.

Elliot Scientific is now distributing Gamma Scientific’s comprehensive range of light and optical test and measurement systems, that are trusted by some of the world’s leading companies and standards organisations, for accurately determining the consistency, power, and colour of light. Gamma Scientific designs and manufactures lab grade light measurement instruments and systems that include:

•  Spectroradiometers
•  Spectrometers
•  Spectrophotometers
•  Goniophotometers
•  Reflectometers
•  Thin Film Measurement Systems
•  Calibration Light Sources – Filament & LED
•  Integrating Spheres up to 3 metres in diameter

ColourimeterIn addition, Elliot Scientific is also offering Optometer equipment from UDT Instruments, a division within Gamma Scientific. This portfolio includes Photometers, Radiometers, Lux meters, Luminance meters, Colourimeters, Photodetectors, and Illuminance meters for photometric and radiometric testing applications.

Night Vision RadiometerGamma Scientific instruments are used in a variety of applications that cover the testing of LEDs, lamps, light fittings and luminaires, lasers and fibre-optics, night vision equipment and visual displays and, uniquely, the single sided inspection of the first surface of any transmissive element.
