The YE0117 is designed for the quick (mainly visual) appraisal of HDTV camera´s transmission characteristics. It consists of a gray background on which circles, gray scales, horizontal and vertical lines are positioned.

In the center of the test chart on a gray background (D=0.75; reflectance = 18%) a white circle with gray scales and resolution wedges is located. On both sides of this central circle four circles with resolution wedges are arranged.

The 16:9 format is marked by four arrows located on the horizontal and vertical central lines. In addition, four arrows located close to the circles on the upper and the bottom edge of the picture mark the 4:3 format. Thus the test chart can also be used for testing 4:3 cameras.

The white central circles shows four gray scales each of 11 steps. They increase in equal linear steps from D=0.15 to D=1.65 and are used for checking halftone rendition of HDTV cameras. Due to the white surrounding area the results may, however, be qualified.

All frequency values in the test chart are indicated in cph (cycles per height). In the central circle three resolution wedges with different frequencies are arranged vertically and horizontally. They reach from 100 to 250, from 200 to 500 and from 400 to 1000 cph. In addition, two resolution wedges angled in 45° generate frequencies of 200 to 500 cph.

In the middle of the test chart and on the left and right sides there are four squares with line rasters that are inclined at angles of 0, 45, 90 and 135°. They generate a frequency of 200 cph. Those line rasters which are inclined at angles of 45° and 135° generate a different frequency (141.4 cph) in horizontal and vertical direction (due to their inclination). The eight outer circles are arranged in such a way that they can be used both for 16:9 and 4:3 format. The larger ones show cross-shaped resolution wedges. The circular rings, which can also be used for checking geometry, are designed for marking the resolution in vertical and horizontal direction. Resolution is shown at 200, 500, 660, 725 and 800 cph.

The outer circles in the four corners have longer resolution wedges. They cross at 500 cph and have markings from 200 to 800 cph.

In the center of the test chart both in the gray and white area bar elements are arranged with a length of 1 (=half the picture-height), 2, 4, 8, 16, 32 and 64 cph. Left to right vertical gray scale there are five additional short bars with 100, 300, 500, 700 and 900 cph.

FAQs About  Other Charts

Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color. 


To take care of a haze meter to make it last longer, ensure that it is cleaned, recalibrated regularly, and stored in a dry, dust-free place. 


Colorimeters is a color measurement device that are used to capture, communicate, and evaluate color. Colorimeters are more affordable, portable, and easier to use, making them a suitable choice for basic color measurement applications, ideal for quick and routine tests.

spectrophotometers offer higher precision and comprehensive data analysis, are better for research, development, and when dealing with complex or highly precise requirements. The biggest difference is in capability and usage. Spectrophotometers are incredibly powerful and can offer more in-depth color measurements than a colorimeter, such as spectral data.

Colorimeters are primarily used for color quality control, while spectrophotometers are used for analysis and formulation. You can choose the appropriate color measurement equipment according to your application needs.


The machine used to measure color is primarily called a colorimeter or spectrophotometer. 

Spectrophotometer: The most common and precise type. It analyzes light reflected/transmitted by an object across the visible spectrum to quantify color accurately. A spectrophotometer can measure colors on smooth or matte surfaces, as well as textured, glossy, mirror-like surfaces, and special effect colors. It measures the reflected light of a sample at a fixed angle (e.g., 45˚) or captures light reflected at all angles to calculate color measurements that closely match what the human eye perceives. Additionally, similar to how humans flip a sample to view colors from different angles, a spectrophotometer is suitable for measuring a variety of materials and surface characteristics. Widely used in industries like paint, textiles, plastics, Chemicals, Pharmaceuticals, and printing. 

Colorimeter: Also called photoelectric integrating colorimeter, a simpler, more cost-effective option. It measures color based on three primary colors (RGB) and is suitable for basic color matching needs. A photoelectric integrating colorimeter is a color measurement device based on the photoelectric integration principle. It directly measures the tristimulus values XYZ of an object's color using three color filters (red, green, blue) and silicon photocells as three sensors. The color measurement principle of this instrument imitates the human eye's mechanism of perceiving the three primary colors (red, green, blue). It corrects the relative spectral sensitivity of the detector through color filters to match the CIE-recommended spectral tristimulus value functions x(λ), y(λ), and z(λ).

Spectrocolorimeter: Combines the functions of spectrophotometers and colorimeters, offering both spectral data and color space values for comprehensive analysis.

Of course. Light booths can determine the color of plastic materials, paints, and coatings used in cosmetics, leather, and even pottery. Light booths used to assess and determine precise color comparison can be used on a variety of materials.


A CAC is a professional light booth designed to provide standardized lighting conditions for visual color assessment. It includes multiple light sources like D65, TL84, and UV.
