NJ-10-100A is designed for operational adjustment and control of TV cameras. It consists of circles permitting rough visual appraisal of scan linearity, grid lines serving the purpose of adjusting registration and wedges serving the purpose of resolution appraisal.

A grid structure consisting of 23 horizontal and 35 vertical lines is arranged on a white background. 3 grid lines each divide the outer 3 grid rows in the middle. The width of the grid lines is 0.15% of the picture width. The large circular line has a diameter of 83 1/3% of the picture height, the 5 small circular lines have a diameter of 25% of the picture height.

4 resolution wedges are arranged in the large circle at angles of 0°, 45°, 90°, and 135° corresponding to signal frequencies of 2-10 MHz. (The marking ends at 8 MHz and 600 lines).

FAQs About  Geometric Test Charts

In a Pantone light box, the tubes last around 2000 to 3000 hours, after which the brightness and color should be assessed for replacement.

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses


Yes. Ultrasonic coating thickness gauges can pinpoint layers within a multi-coat system. Users can examine the separate thicknesses of a primer, base coat, and clear coat. In contrast, magnetic and eddy current gauges usually measure the overall thickness of the coating. 

Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.


Gloss paint can be identified by visual inspection and using a gloss meter. The high gloss paints are shiny and reflective like a mirror, satin or eggshell has a soft sheen, whereas the matte paint is non-reflective with very little or no reflection.


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.
