The multiple sensors and optical grating make the CL-500A illuminance spectrophotometer ideal for measuring and evaluating CRI which is the calculation of color-rendering properties of light sources and lamps while providing objective criteria. This device will display and measure the CRI (Ra) and individual indices; R1 through R15. One of the many benefits of a sensor based detector is the capacity to present spectral distribution in graphic format. Since the CL-500A illuminance spectrophotometer is sensor based, using this instrument is a perfect option for measuring narrow bandwidth light sources such as Ultra High Pressure Lamps (UHP), LEDs, OLEDs, and many others.
The immediate availability of photometric units makes them efficient on a moment’s notice; illuminance in lux and foot candle, chromaticity in XY and uv color space, Duv, color temperature (CCT) in Kelvin, dominate wavelength, tri-stimulus values XYZ, and excitation purity are among the viabilities included.
The portable, light weight design encourages use with multiple applications throughout the lighting industry. The CL-500A illuminance spectrophotometer can be used with or without a computer and has the capability of use by itself anytime color temperature lamps, LEDs, and/or CRI need to be measured. The ability to directly check peak wavelength and spectral irradiance waveform make this device a desirable addition to any kit.
