Image Quality Testing Solutions


As a global leader in image quality testing, we leverage our expertise in image quality testing, equipment, and knowledge to help companies across industries worldwide improve their imaging devices.

Standard camera testing typically covers multiple image quality metrics such as resolution, texture detail retention, noise, dynamic range, color accuracy, distortion, shading non-uniformity, and chromatic aberration. Camera systems often require comprehensive multi-dimensional evaluation.

Through the efforts of our R&D department and the introduction of high-precision production equipment, Threenh has gained the capability to customize various types of test charts. We can produce all kinds of transmission-type test charts (e.g., film charts) and reflection-type test charts according to clients’ specified drawings. Commonly used camera testing charts such as resolution charts, color bar charts, distortion test charts, grayscale charts, and dynamic range test charts can all be customized, significantly reducing costs for high-tech enterprises globally.

FAQs About  Test Charts

Once ignited, the gauge will select the correct substrate mode. The probe should be placed flat on the coated surface. The thickness of the coating will show on the screen. Measurements should be taken on different areas of the surface to ensure accuracy.


An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

Consistency in calibration is important to account for imbalances arising from wear and tear of the probe, probe pressure, variation from the environment, and fluctuations in daily usage. This is also necessary to maintain the best quality to various international standards.


Inconsistent results from a haze meter can stem from issues like calibration, dusty haze meter optics, inadequate power supply, and improper measurement technique. If you have any questions, you can contact our Haze measurement experts


You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.

By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.


Threenh colorimters are used across various industries to measure, analyze, and control color accuracy and consistency:
