Spectrophotometer from Konica Minolta uses multiple sensors

The CL-500A is a compact, lightweight illuminance spectrophotometer for illuminance measurements and spectral evaluation of LEDs, organic LEDs (OLEDs), and electroluminescence (EL) illumination. It uses multiple sensors and an optical grating to measure color rendering index (CRI) and display the CRI and individual indices from R1 through R15. It can also display spectral distribution in graphical form.

PRESS RELEASE

CL-500A ILLUMINANCE SPECTROPHOTOMETER

The CL-500A is a compact, lightweight illuminance spectrophotometer that can be used not only for illuminance measurements but also for spectral evaluation of high class next generation lamps such as LEDs, OLEDs and EL illumination.

The CL-500A makes use of multiple sensors and an optical grating which enables it to measure and evaluate CRI or Color Rendering Index. CRI is a quantification of the color-rendering properties of a lamp or other light source, and was defined to provide objective criteria. The CL-500A will measure and display the CRI (Ra) as well as the individual indices from R1 thru R15. Another benefit to using a sensor based detector is the ability to display spectral distribution in graphical form. The fact that the CL-500A is a sensor based instrument means it is well suited to measuring narrow bandwidth light sources including LEDs, OLEDs, Ultra High Pressure lamps (UHP), etc.

Photometric units are also available at any time. These include illuminance in lux and foot-candle, color temperature (CCT) in Kelvin, chromaticity in xy and u’v’ color space, tri-stimulus values XYZ, Duv, dominant wavelength and excitation purity.

Its lightweight and portable design allows it to be used for multiple applications within the lighting industry. It’s also a stand-alone instrument which allows it to be used without the need of a computer. The CL-500A can be used by itself virtually anywhere CRI or color temperature of lamps and LEDs need to be measured. In addition, the spectral irradiance waveform and peak wavelength can also be checked directly on the unit.

With the standard data management software (CL-S10w) included you can download measurement data directly to Excel as well as display spectral irradiance values, spectral waveform, chart color rendering indices and enable LED Binning function. Multi-point measurements are also possible by connecting up to 10 CL-500A units together.
