Best Luminance meter is a light color measuring instrument, that is, a measuring instrument for measuring brightness and chromaticity. For Best Luminance meter at a certain measuring distance, the larger the field of view, the larger the target point to be measured. When testing, select the field of view that is compatible with the area of the target to be tested. If the field of view is too large or too small, it will be affected. Come a larger error. The imaging Best Luminance meter uses an area array CCD as a light detector. It only needs to sample once to measure the brightness of millions of points in the plane at the same time, which is equivalent to millions of aiming points. , The imaging Best Luminance meter can measure the angle of view at any angle, and the angle of view is flexible. However, compared with the aiming type Best Luminance meter, the V(λ) matching error of the imaging Best Luminance meter is more difficult to control. In order to meet the general measurement requirements, the V(λ) mismatch error should reach the first level or above. The Best Luminance meter is a colorimeter first, and it must first be able to complete the color coordinate test of the sample.

The above is a brief introduction to some knowledge about Best Luminance meter.
