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).

UTILIZATION

  • The test chart is designed for operational adjustment and control of TV cameras.

A benchtop spectrophotometer is not universally better—it outperforms portable units in precision and lab testing, while portable models win for on-site flexibility. Which one is better depends entirely on your testing scenarios, accuracy requirements and workflow.


Benchtop Spectrophotometer Advantages

  • Higher measurement accuracy & repeatability, excellent inter-instrument agreement

  • Supports full-spectrum analysis, more geometric optical designs

  • Larger testing aperture, compatible with curved, textured and bulk samples

  • Ideal for laboratory QC, R&D, formula matching and standard color calibration

  • Stable performance, less affected by external light and environment


Portable Spectrophotometer Advantages

  • Compact, lightweight, test anywhere anytime (production line, warehouse, on-site inspection)

  • Fast one-click measurement, no fixed power and lab space required

  • Perfect for incoming material inspection, on-line production spot check, field color comparison

  • Lower cost and easier to operate for frontline workers


Which One Should You Choose?


Choose benchtop if you need:

Lab R&D, high-precision color grading, standard sample database establishment, strict quality control for cosmetics, plastics, textiles and food.


Choose portable if you need:

On-site rapid detection, production line mobile sampling, outdoor and on-location color measurement.


Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

A service is made up of tub replacement, light source recalibration, internal cleaning, verification of service and color certification retention so that all compliance color standards are retained. 


To determine haze, haze meters are used in multiple industries such as plastic, glass, film, coating, and displays. This ensures that all optical quality of the product is in the appropriate specification, including aesthetic compliance and meeting the intercontinental quality standards.
