Description

Perfect solution for measuring light-source color and illuminance

The Chroma Meter CL-200A is a compact, lightweight, handheld instrument for measuring the color and illuminance of light sources (including new LED and EL light sources) and displaying the results in terms of tristimulus values, illuminance, chromaticity, dominant wavelength, excitation purity, correlated color temperature, and difference values from a target.

The included software CL-S10w adds further versatility, including LED ranking, correlated color temperature, and multi-point or user calibration.

 

Principal applications

  • Checking the illuminance, chromaticity, dominant wavelength and correlated color temperature of various kinds of light sources including organic EL lighting (OLED), LEDs, etc.
  • LED billboard development, quality control, and maintenance
  • Evaluating the light distribution characteristics of LED illumination modules
  • Evaluating the illuminance distribution of lighting fixtures
  • Building and interior lighting research
  • Spatial lighting production and adjustment
  • Color-viewing cabinet maintenance
  • Projector light source research and color inspection
  • Checking environments for psychological research experiments

Features

Compact, easy to carry, and battery-powered

The CL-200A body fits in the palm of your hand, and is easy to carry along to take measurements where needed. It can be powered by 2 AA-size batteries (or by an optional AC adapter).

 

Easy measurement of correlated colour temperature

The CL-200A can measure correlated colour temperature and the difference from the blackbody locus Δuv, values which are used to describe the colour of light sources. The colour temperature of light is defined as the absolute temperature (in Kelvin) at which a blackbody would emit that particular colour of light.

 

Ideal for quality control of white LED lamps

White LEDs are usually made up of a blue LED which has been coated with a yellow phosphor material, so that the blue light emitted by the LED mixes with the yellow light emitted by the phosphor to create white light. Since the spectral emission distribution of the blue light emitted by the LED varies slightly for each unit, variations in the resulting white light will occur. Because of this, for white LED’s it is important to control not only the brightness but also the colour. The CL-200A can measure both the chromaticity from the phosphor and also inspect the output light quality of the final white LED lamp assembled from multiple white LED’s.

 

LED ranking function (Binning)

When LED’s are manufactured they are broadly grouped into colour categories such as red, red-orange, cyan, cool white, warm white, etc. In combination with the CL-S10w software, the CL-200A allows to rank the quality ranking range of white LED’s.

 

Multi-point measurements

The receptor head can be detached from the main body and then connected at a distance using  up to 30 measuring heads for multi-point measurements over a large area. In combination with the CL-S10w software one can simultaneously control all measurement points.
