LED light color fast analyzer

It is used to quickly measure the luminosity, chromaticity and electrical properties of LEDs. It is equipped with a constant voltage constant current source, a fast spectrometer and a photometer. It can realize LED forward voltage, forward current and reverse voltage without connecting to a computer. Measurement and display of parameters such as reverse current and luminous flux.
After communication with the computer, the measurement and display of parameters such as color temperature, color rendering index, dominant wavelength, peak wavelength, chromaticity coordinates, color tolerance, color purity, and red ratio can be realized.
Suitable for LED production lines, rapid testing of R&D and quality inspection departments.
