Illuminance Spectrophotometer CL-500A

A hand held Illuminance spectrophotometer ideal for the measurement of LED  lighting. The CL-500A provides full spectral data from 360-780nm allowing accurate assessment of color rendering and other measures such as lux and color temperature that are traceable to international standards.

Applications

  • The CL-500A is a compact, lightweight illuminance spectrophotometer that can be used not only for illuminance measurements but also for spectral evaluation of light sources including next-generation lamps such as LEDs, OLEDs and EL illumination.
  • The CL-500A makes use of multiple sensors and an optical grating to measure CRI (Colour Rendering Index). CRI is a quantification of the colour-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 through to R15. The fact that the CL-500A is a spectral sensor based instrument means it is well suited to measuring narrow bandwidth light sources including LEDs, OLEDs, Ultra High Pressure lamps (UHP), etc. Another benefit of the sensor based detector is the ability to display spectral distribution in graphical form.
  • Photometric units including illuminance in Lux and foot-candle, colour temperature (CCT) in Kelvin, chromaticity in xy and u’v’ color space, tri-stimulus values XYZ, Duv, dominant wavelength and excitation purity can also be measured.
  • The lightweight and portable design of the CL-500A allows it to be used for multiple applications within the lighting industry. The built-in display enables the CL-500A to be used as a stand-alone instrument without the need for a computer. The highly portable CL-500A can be used virtually anywhere CRI or colour temperature of lamps and LEDs need to be measured. The spectral irradiance waveform and peak wavelength can also be viewed directly on the unit.
  • The standard data management software (CL-S10w) included with the instrument can download measurement data directly to Excel as well as display spectral irradiance values, spectral waveform, chart colour rendering indices and features an LED Binning function. Multi-point measurements are also possible by connecting up to 10 CL-500A units together. For more specialised applications the software development kit is available free of charge to provide fine control over data and application.
