Practical instrument with high potential

The GL SPECTIS 1.0 optical system uses a miniature collimating lens with nano-imprint of diffraction lines and a CM OS image sensor working in the range of 340-750nm. It is a miniature low stray light system providing a 1.7nm data acquisition interval which is ideal for the measurement of LEDs, OLEDs and other light sources in the visual range. The electronic board ensures the proper speed of data transfer and very low noise. The temperature sensor installed on the board monitors the change of the ambient temperature and its influence on the measurement stability. The SP X driver software includes any necessary correction procedures to reduce stray light, bandpass error, noise level and background level to achieve the best spectra representation and highest measurement accuracy. The data acquired are calculated according to CIE norms to obtain the right color calculation for LED and other light sources.
