color calibration System
The PhotoMeter-20 is equipped with a filter wheel for color measurement. Luminance and color coordinate can be measured in a spatially resolved way. Surpassing standard chroma meter which uses photocell as light sensor and can only measure a point, PhotoMeter-1 uses CCD sensor and provide complex evaluation of light sources and illuminated scenes by measuring luminance and color distribution within the whole field of view.
Photometer-20 composed of 16bit scientific cooling CCD sensor. The high quantum efficiency, wide dynamic range (70db) and low noise (<0.02 electron per second) performance make it can distinguish tiny biases and get accurate measurement result.
PhotoMeter-20 is equipped with metrological optical circuit which is adapted to the CIE color matching functions of the 2° standard observer (CIE1931). Absolute brightness measurement accuracy reaches 3% (for standard illuminant A). Absolute color measurement accuracy reaches 0.003 (for standard illuminant A).
PhotoMeter-20 is equipped with Nikon standard F mount lenses adaptor. Customer has wide range of lenses choice based on measurement sense size and measurement distance.
PhotoMeter-20 can be used for Laboratory measurement, production line display equipment quality control, industrial automation and field display equipment brightness and color uniformity calibration.
