Engineered for precision MTF measurement in AR/VR and near-eye systems
- Human-eye mimicking, 5 mm external aperture lens
- 14 ° FOV
- 0 to 4 dpt refocus, motorised
- diffraction limited
Meet SharpEye 14 MTF, a fully motorised, refocusable diffraction-limited lens:
As an external aperture lens, SharpEye 14 MTF is well suited for testing MTF of near eye displays or entire AR/VR headsets.
