Tonight, aboard the USS Midway in San Diego, Gamma Scientific will be among the finalists in the Solid State Lighting Enabling Technologies and Test category at this year’s Sapphire Awards for their 940 LED-200 Series Goniometer.
The 940 LED-200 Series Goniometer is optimised for the precise measurements of angle dependent spatial radiation properties of LEDs and small luminaires. It can accommodate sample sizes up to 200 mm in diameter, and can be combined with a Gamma Scientific Spectroradiometer or UDT Series photometer.
With a spectroradiometer, the goniometer can measure luminous flux, colour coordinates and CRI; while a photometer connected goniometer can provide fast measurements of spatial light distribution.
- Rapid, precise characterisation of of spatial light distribution
- Accurate measurement of LED luminaires, lamps and modules
- Models optimised for specific sample sizes
- Conform with CIE, DIN and IES standards

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.
For more details, please contact us.
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.
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.

The Elliot Scientific January newsletter is now available. In this issue we get smart with clever products for optical fibre inspection from EXFO and mobile retroreflectometry from RoadVista, plus a remote control app for the CryoLab from Kryoz Technologies. Gamma Scientific sharpens its GS-1290 spectroradiometer specifications and Elliot Scientific uploads all of last year’s newsletters and announces Photonics West dates and details.

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:
- 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.
Please contact us for more details.
Combining the leading-edge sensitivity of a backside-thinned CCD detector with Gamma Scientific’s industry-renowned RadOMA opto-electrical platform, the GS-1290-NVIS exceeds all requirements outlined in MIL-L-85762A and MIL-STD-3009 for the characterisation of night vision compatible interface lighting in aircraft.
The GS-1290-NVIS represents the state-of-the-art in speed and accuracy in a commercially available spectroradiometer. Measurements that required a few minutes in the past with scanning grating spectroradiometer systems can now be performed in a matter of seconds.
