DMS-1500H Optical Property Test System
Six-axis automatic rotation, high degree of automation
Typical application scenarios
DMS-1500H is a display device photoelectric characteristics comprehensive measurement system developed by EVERFINE based on many years of optical equipment research and development and production experience. The system has complete measurement parameters, high measurement accuracy, and high degree of automation. The system can be used to measure luminance, luminance uniformity, contrast, viewing Angle, spectrum, color coordinates, chromaticity uniformity and other optical and electrical properties of 3-15 inch OLED display. With the instantaneous characteristics measuring device, it can also measure the flicker, response time, gray scale response time, preheating time and other instantaneous characteristics of the display screen. With the ambient light test component, it can measure the ambient light characteristics of the display screen, including transmission, mirror reflectance, diffuse reflectance, ambient light contrast, ambient light gamut and other parameters.
Main characteristics
1. High degree of system automation
Six-axis rotation device, mechanical rotation, high positioning accuracy, can achieve the display Angle of view, uniformity, ambient light and other characteristics of the accurate test.
2.Integrated spectrum, luminance, chromaticity measurement
Equipped with high-precision Spectral Radiance Colorimeter, luminance, spectrum and chromaticity measurement functions in one, the highest sensitivity of up to 0.0005 cd/㎡, low luminance can also maintain excellent accuracy and speed, is the standard machine for luminance and chromaticity measurement.
3.Simulate different kinds of ambient light
Optional hemispherical diffuse reflection lighting source, whole sphere diffuse reflection lighting source, integrating sphere directional light source for display reflectivity and ambient light contrast test evaluation, simulate the screen display characteristics under ambient light.
