Mer-QAM160
Mer- QAM160 is the first independently developed fast angle measurement lens in China. It can accurately and reliably measure brightness and contrast at a large field of view angle of 160°. It is widely used in the detection of displays and has the following core advantages:
● The first domestic independent research and development
● 160° large field of view
● One-time full inspection, fast and accurate measurement
●Considering small-size LEDs and MicroLEDs
● Both low cost, high performance and flexibility
● Designed specifically for R&D and quality departments
Features
The fast angle measuring lens Mer-QAM160 has many core technical advantages:

Display screen detection
It can be used with a spectrometer or colorimeter to detect and evaluate the angular distribution of color, brightness and contrast of flat panel displays, light sources and their components. It is suitable for a wide range of display types, including displays based on LCD and OLED technologies, as well as backlight displays, etc.; the minimum diameter of the screen can be measured is 6mm, and both point and surface light sources can be detected.

160° large field of view
Within a large field of view angle range of 160°, complete viewing angle data can be collected through a single measurement, and the brightness and contrast can be accurately and reliably measured.

One-time full inspection, fast and accurate measurement
The luminous angle of the full screen can be measured at one time without multiple measurements for image stitching, quickly providing accurate measurement results, making it an ideal choice for R&D and quality control applications.

Take into account both small size LED and MicroLED
Strict control of aperture aberration can take into account the measurement of the angle information of the LED lamp bead chip and the extended luminous screen.
