Illuminance Spectrophotometer CL-500A、CRI Illuminance Meter CL-70F

CL-500A Illuminance Spectrophotometer is used for illuminance measurements and the spectral evaluation of high quality, next generation lamps including OLEDs, LEDs, and EL illumination.

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.

The CL-500A comes standard with the CL-S10w Data management Software capable of downloading directly into Excel. The device features a display that shows data such as spectral irradiance values, chart color rendering indices, spectral waveform, and enabled LED Binning Function. Two to ten CL-500A can be daisy-chained for multi-point measurements.
