The NED-LMD M-Series product range delivers the ideal all-in-one solution for high speed, high resolution, and high accuracy testing of near-eye displays. The M-80 model configuration is the world’s first integrated medium field of view (MFOV) quality analysis solution that matches human eye resolution and is specifically designed for high volume product environments. It features a custom-designed motorized focus lens which covers 65o (H) by 48o (V) FOV for high fidelity 3D spatial and spectral characterization of Virtual Reality, Augmented Reality, Mixed Reality and Heads-Up Displays (VR, AR, MR, and HUDs). The systems conform to the latest standards being developed by the ICDM committee of the SID and IEC.
