ECTS-TC series Medical Endoscopy Test Chart——Used with medical endoscope test systems for medical imaging system image quality parameters, in accordance with industry standards (e.g. YY0068.1)

ColorSpace for medical and industrial endoscopic imaging systems,The image quality test system CS-ECTS is specially developed and equipped with the corresponding endoscope test chart (ETCS-TC), which can be used to test and analyze the angular resolution、MTF、spatial frequency、signal-to-noise ratio, color reproduction, AWB、Distortion 、FOV、Shading、Dynamic range、static image latitude/brightness response characteristics、lens spectral transmittance and other parameters. It can be used to test the color and brightness uniformity of the endoscope's own light source with a reflective color test chart.

Meets industry standard requirements such as:

· YYT/1587：Medical endoscopes-Video endoscopes

· YYT/1603：Medical endoscopes-Endoscopes supply units-Video camera system

· YY0068.1：Medical Endoscopes-Rigid Endoscope-Part1：Optical properties and test methods

· YY 1298：Medical endoscopes-Capsule endoscopes
