Portable solution for measuring light-source colour and illuminance

The CL-500A is a compact, lightweight illuminance spectrophotometer which can be used for evaluation of light sources including LED and EL illumination.

The advanced sensor measures, illuminance, chromaticity, colour temperature and CRI (Colour Rendering Index) of virtually any light source. The on-board display, built in battery, tripod mounts and USB connectivity mean that it is suitable for use in the lab, production or out in the field.

 

Main applications

  • Spectral evaluation of light sources including next-generation lamps such as LEDs, OLEDs and EL illumination
  • Checking the illuminance, chromaticity, dominant wavelength and correlated colour temperature of light sources
  • LED billboard development, quality control, and maintenance
  • Evaluating the illuminance distribution of LED modules and lighting fixtures
  • Building and interior lighting research
  • Spatial lighting production and adjustment
  • Colour-viewing cabinet maintenance
  • Projector light source research and colour inspection
  • Checking environments for psychological research experiments

Features

Features
  • Spectral sensor provides enhanced Illuminance information: The device firmware provides CRI data alongside dominant wavelength and other features useful for making the most of modern lighting technologies. Using the software, alternative scales (CQS) can be added, providing additional utility where the quality of lighting may have raised importance for Aesthetic or safety reasons.
 
  • Measure scotopic and photopic illuminance: The spectral sensor allows for scotopic illuminance to be measured and S/P ratio measured on the onboard display.
 
  • Compliant with international standards: The CL-500A conforms to both DIN 5032 Part 7 Class-B and JIS C 1609-1:2006 General Class AA standards which ensure high accuracy illuminance measurements.
 
  • Expanded connectivity and integration options: The CL-500A can be connected by USB to a PC to benefit from the included data management add-in for Excel, allowing the user to operate the device, save and analyse data. More advanced needs can be met using the SDK, which in combination with the tripod mounts enables the integration into automated systems and production environments.

CL-500A Illuminance Spectrophotometer

Applications

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.
