The VDM-1800R near eye display optical testing system is primarily used for measuring virtual image parameters of near eye display devices such as AR/VR. The measurement items encompass virtual image distance, field of view angle, eye box, brightness, chromaticity, uniformity, color gamut, distortion, MC, and more. Designed in accordance with the relevant requirements of the international standard (IEC63145-20-10), the VDM-1800R utilizes optical measurement technology that simulates human perception, offering fast measurement speed and high accuracy.
