RGB Laser Luminance Meter TM6103

Balancing the measurement capability of a spectral analyzer and the ease of use of a colorimeter

TM6102, TM6103, and TM6104 are optical measuring instruments capable of simultaneously measuring the centroid wavelength and optical power of RGB composite waves. If you set the target values for luminosity and chromaticity, as well as the allowable ranges, you only need to adjust the radiance of each RGB to the specified range to complete the "white balance adjustment".

RGB laser specific, the most suitable for measuring the brightness of displays with a field of view angle of 22 °. It is a light tester developed to accurately measure the "white" of laser displays.

The RGB laser luminance meter TM6103 is the first luminance meter to adopt a new method of accurately measuring laser, the "separation of center of gravity wavelength method". Moreover, it is equipped with a "white balance adjustment auxiliary function" that can reduce the white balance adjustment time by half during shipment. By adjusting the RGB light sources separately, the target light source "white" can be produced.
This product is an RGB laser specific light tester designed to accurately measure next-generation displays such as HUD (Head Up Display) or wide color gamut displays that use laser light sources.

RGB laser specific illuminance meter TM6102

Why is it dedicated to RGB laser?

For example, in order to measure current, our company provides over 20 different measuring instruments. Due to factors such as frequency, voltage value, environment, and cost, natural deviations will increase. The emission of laser light is different from that of LED light. In order to measure the laser light source, if there is no most suitable measuring instrument, unexpected results may be obtained.
Represented by laser displays, applications using laser light sources require miniaturization and wide area color representation. With the development of RGB monochrome lasers, more accurate color measurement and clearer color representation are needed compared to the LED era.

The RGB laser luminance meter TM6103 is a luminance meter specifically designed for laser light sources. That is to say, it is impossible to measure the wide spectral width of light such as LED or lamp sources. Moreover, even with laser light sources, wavelength changing light such as phosphorescence is difficult to measure.
However, if measuring a simple laser source, not only monochromatic laser, but also RGB composite incidence can be accurately measured. Please compare the measured values of the wavelength near the center of gravity of the spectrometer and the RGB laser luminance meter that considers the usability of the colorimeter with "light".

Precautions for laser measurement, the laser spectrum will have multiple peaks

Compared to visible light with wavelengths ranging from 400nm to 700nm, the spectrum of laser is very narrow. Only monochromatic lasers are tested, and such complex spectra are often seen (as shown in the figure on the right). Due to the difference in center of gravity compensation and peak wavelength, chromaticity needs to be calculated, especially for laser spectra that fluctuate with temperature. In order to accurately measure, it is not only necessary to use a high-precision spectrometer, but also to measure the center of gravity wavelength that reflects fluctuations.

The topic of laser photometry: the boundary close to the isochromatic function

Generally, the tristimulus value test method and other colorimeters are combined with a filter to match the isochromatic function by adjusting the filter (physical filtering). The spectral wavelength of monochromatic laser is very narrow, and the approximation error of the color function and the inherent error of the filter (individual differences) will be significantly superimposed on the measurement results.

The "Separate Center of Gravity Wavelength Method" developed for laser metering

TM6103 measures the necessary physical quantities (centroid wavelength, optical power) for color measurement, and then calculates them through theoretical calculations using optical properties such as chromaticity and photometry.
Therefore, as the wavelength of the center of gravity changes, it is not affected by the approximation error caused by the wavelength range of the optical filter, and laser color measurement can be performed correctly. It is the first luminance meter that simultaneously measures the center of gravity wavelength of a spectral analyzer and considers the usability of a colorimeter.

Adjusting navigation settings through white balance and halving work hours

The white balance adjustment assist function indicates the optimal path to the "white" target on the laser display screen. Automatically calculate the required radiation of each RGB light source in the "white" of the target from RGB multiplexing (RGB3 color laser light source) and adjust the target range.

Adjusting the color (chromaticity) and brightness (light measurement) of the target can indicate the range of RGB radiation levels. Significantly reduced the number of hours required to balance the "chromaticity" and "photometry" that were previously difficult to adjust simultaneously using three stimulus methods. The allowable range (upper and lower limits) of the target value is linked, and the range can be automatically adjusted, which is HIOKI's exclusive navigation adjustment function

Monitoring application

RGB Laser UTILITY TM6103/TM6103/TM6104 is the same

TM6103 can help you solve the problem of laser metering!

Have you ever experienced a situation where the chromaticity display is the same but appears different?

Have you ever encountered a situation where there was no problem measuring LED light sources or light bulb light sources before, but there was color difference when measuring lasers? Adjust the white balance by visual inspection for unknown reasons.
In order to achieve a white balance of Δ xy=0.001 for wide color gamut televisions, the ability to measure wavelength is particularly important. When measuring a laser with a spectral amplitude of several nanometers, insufficient spectral wavelength amplitude and inability to accurately calculate the centroid wavelength can both affect chromaticity.

If you have trouble with laser measurement, you can try the RGB laser brightness meter TM6103.
