Setting the Calibration Mode

Calibration Modes

The CL-200 CHROMA METER offers two calibration modes: NORM and MULTI. Select the appropriate mode using the CAL MODE switch. The calibration mode should be changed only while the power switch is on. If the position of the CAL MODE switch is changed while the power switch is off, the change will not take effect.
When you select this mode, the CHROMA METER uses reference light source A as the calibration source. This mode is recommended for measurement of normal light sources (light sources with continuous spectral distributions).
When you select this mode, the reference light source is an LCD projector with a UHP (ultra-high-pressure) mercury lamp. The CHROMA METER calibrates R, G, and B tricolor components separately, and then implements W correction. This mode allows for high precision measurement of all colors. The mode is appropriate for measuring a tricoloraddition light source whose spectral distribution is approximately the same as that of the reference source.
Setting CFs for Each Mode
The CL-200 CHROMA METER can store CFs (correction factors) for both calibration modes, and can apply these to your measurement results. You can use this feature to correct for disparities among different CL-200s or to adjust calibration arbitrarily as needed. After setting the CFs, you can use the [CF] key to switch use of CF correction ON or OFF.
Setting the CFs for NORM calibration mode
You set the CFs by taking a measurement of a known light source, then keying in the corresponding known values. For details, see page 26.
Setting the CFs for MULTI calibration
You set the CFs by measuring the three color components (R, G, and B) of the light source (a CRT or LCD projector) and then keying in the known reference values. You can also measure the W component and key in a W reference value, allowing for W correction as well. Setup of CFs for MULTI calibration mode is carried out by (optional) CL-S1w data management software. For information about how to use the CL-S1w to set these CFs, refer to the CL-S1w online help.

For projector light-source research and color inspection
The CL-200A can be used to measure the white balance and uniformity of microprojectors, etc. with internal LED light sources.

The CL-200A enables quality control of the LED modules for digital signage to be performed easily. If modules with different color tones are used together, the billboard will look mottled, but by measuring the chromaticity and color temperature of modules using the CL-200A and selecting modules based on measured values, billboard uniformity can be achieved.

For accurate measurements of color temperature, use the CL-200A!
Measurement accuracies of CL-200A and photographic color meter
When measuring light sources with non-continuous spectrums such as LEDs, etc., accurate illumination color temperature is particularly required. The CL-200A can measure color temperature accurately.

CL-200A

The CL-200A has sensors that closely match the color-matching functions defined by the CIE (International Commission on Illumination), enabling precise color measurement. The measurement results can be displayed in various color notations such as "Correlated color temperature and uv" according to the application.

Photographic color meter

In order to take more beautiful pictures, it is sometimes necessary to attach filters in front of the camera lens to compensate for the color of the light illuminating the subject. A photographic color meter is a meter used to select the appropriate filters, with the sensitivity of its sensors adjusted to match that of the film or digital camera sensor. In addition, because it uses photographic color temperature, which is calculated based mostly on the blue/red balance of the illumination, large errors may occur if it is used to measure light sources with non-continuous spectrums.

Color temperature and correlated color temperature

Color temperature

When an ideal blackbody* is heated, it begins to emit light, and as the temperature increases the color of the emitted light changes from red to yellow to white. Since the color of the emitted light is determined by the temperature of the blackbody, the color of the light emitted by the blackbody can be expressed as the absolute temperature of the blackbody (in Kelvin). This color notation scale is called "color temperature". For example, a 7000K color would be the color of the light emitted by a blackbody heated to 7000K. Figure 1 shows the color of light emitted by a blackbody at various temperatures plotted on an xy chromaticity diagram. This curve is called the "blackbody locus"; "color temperature" expresses a color on this blackbody locus.
Correlated color temperature
Since the color of white light emitted by illumination equipment and displays is generally close to the blackbody locus, the color of such light sources is normally expressed using "color temperature". However, the color of such light sources is not directly on the blackbody locus. Because of this, a way to enable similar color expression for colors within a larger region close to the blackbody locus was devised. This is called "correlated color temperature", and the larger region is shown by the isotherms on the xy chromaticity diagram in Figure 2. To accurately express the correlated color temperature of a light-source color, it is necessary to state not only the correlated color temperature but the difference from the blackbody locus, normally in terms of uv.

*Blackbody An ideal radiator. A body which completely absorbs all incident electromagnetic radiation. Although a perfect blackbody does not actually exist, coal is a familiar object that acts similarly.

General Reference Information
Measurements in the LED manufacturing process
When made from blue LED and phosphor
The blue light emitted by the LED mixes with the yellow light element Blue light emitted by LED emitted by the phosphor to create white light.
Yellow light emitted by phosphor Package Electrode LED element Phosphor

Problem:

Since the spectral emission distribution of the blue light emitted by the LED varies for each unit, variations in the resulting white light will occur. Since usually LED lamps use several LEDs, control of color mixing is necessary.

General solution:

Measure the spectral emission characteristics of each LED element and rank them accordingly. Measure the emission characteristics of the phosphor and rank accordingly. r Combine the ranked LED elements and anked phosphor materials to achieve the desired white light. Inspect the output light quality of the final assembled white LED lamp.

Wavelength (nm)

Variations in white light
How the CL-200A can help: The CL-200A can measure the chromaticity from the phosphor and also inspect the output light quality of the final assembled white LED lamp.
LED total flux measurement system
This system combines our top-of-the-line Spectroradiometer CS-2000 modified for illuminance measurement with an LED total flux measurement adapter to create an LED measurement system that utilizes a spectral measuring instrument conforming to CIE 122-1996 as the receptor. The total flux emitted in all directions by the LED is diffused by the integrating sphere and received for measurement by the spectroradiometer. This system conforms to CIE 127:2007. Since the spectral response of the receptor matches the CIE spectral luminous efficiency function V(), there is no need to perform troublesome color correction. To enable accurate measurements, a self-absorption compensation function is provided to compensate for the reduction in integrating sphere output due to self absorption of the light source when it is lit inside the integrating sphere.
