Ideal for the spectral evaluation of lamps and displays
GS-1160 Handheld Spectroradiometers
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 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.
