The test chart consists of a blank film between two glass panes.

The test chart is designed for shading measurement under the same lightning conditions as other transparency measurements.

It is possible to perform shading measurements on illuminator (LG2, LE6) without any chart. But then lightning conditions are different to other measurements with test transparencies. By using a test transparency the light intensity of an illuminator changes.

This is caused by two superimposed factors
a) the filter effect of the film and glass (25% light absorption) and
b) the light remission of the transparency ack in the illuminator

While factor a) is predominat with th LG2, the remission factor b) is predominant with the lightning sphere LE6, i.e. the light intensity rises significantly when a test chart is inserted. To carry out shading measurement under the same lighting condition as other measurements the use of the YE0178 is essential.

Definition of white shading or white level uniformity

Determination of maximum white level variations in various areas of the picture, when the camera is directed at an evenly illuminated test chart.

FAQs About  Other Charts

Lightbooths come in different dimensions. A typical tabletop model occupies 0.5-1 m². The bigger industrial variants take up 2-4 m².  If you have special requirements, we can customize the product according to your size


D/8°and 45°/0°are two kinds of illumination geometry with different optical geometry design. D/8°illumination geometry is more widely used for the color comparison and measurement of high-gloss materials; 45°/0°illumination geometry is mainly used in printing and packaging industries. 

The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.


Of course! Many portable, battery operated, and lightweight coating thickness gauges are available for on-site and field inspections. They provide quick and accurate results and portable gauges are ideal for construction, automotive, and industrial environments.


To quantify color change, take the original L*a*b* values of a sample, and reread after exposure or processing. Compute the difference as 1/2(Emut1 Emut2). The larger the value of ΔE, the more obvious the change of color is, which can be used in quality or stability testing.
