New spectrometer quantifies light flicker measurements

27-12-2018 | Saelig | Test & Measurement

Saelig Company has introduced the GL Spectis 1.0 Touch Flicker Spectrometer, an upgraded version of the very successful handheld Spectis 1.0 Touch Spectral Light Meter. This device can now measure the increasingly important parameter of light flicker in addition to the extensive range of standard photometric and colourimetric values already available. The Spectis 1.0 Touch Flicker Spectrometer is now equipped with additional electronics and a fast photodiode to measure flicker frequency, flicker index, and flicker ratio. Created and developed in discussion with industry leaders and standards committees, this device gives all the measurement quantities needed to accurately measure and understand flicker.

The new device is suitable for measuring flicker in the signal range 0.1Hz-12.5kHz. The user can take measurements of light sources and LED floodlights. To fully characterise and compare light sources, the device can process recognised flicker parameters such as flicker frequency, flicker index and flicker factor. The device can also be used to capture other photometric and colourimetric data such as illuminance, colourimetric locus and colour rendering index, displaying the analysis results on the colour touchscreen. The GL Spectis 1.0 Touch Flicker can be used to detect, characterise, and ultimately avoid flicker issues. Covering a particularly wide range of frequencies, this device offers accuracy equal to many laboratory devices.

The company's light measurement instruments were recently used during installation of the new LED playing field lighting at Chelsea Football's Stamford Bridge Stadium, UK. Mike Simpson, director of engineering and design at Philips Lighting, stressed that "The GL Optic device allows us to rapidly and accurately assess the quality of LED-based lighting installations. The GL Spectis 1.0 Touch is a very fast spectrometer and easy to use in the field".
