Near Eye Display Test system

  • Product No:NED-LMD M Series
  • Manufacturer:Gamma Scientific

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.

It features a custom-designed motorized focus lens which covers 65° (H) by 48° (V) FOV yielding >180 pixels/degree resolution 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.
