Optotune Focus Tunable Lens ML-20-37

The Optotune ML-20-37 manually focus-tunable lens features a 20mm clear aperture and is designed to have its lens curvature change between convex (+18 dpt), flat (0 dpt) and concave (-18 dpt) by the rotation of the outer adjustment ring. The rotation mechanism is extremely durable (>100’000 rotations), linear and low in torque, allowing for reliable motorization that reaches a repeatability of typically 0.1 dpt.

The ML-20-37 is available with and without C-mount adapter.

Key advantages:

  • Large optical power range of 36 dpt
  • Zero holding power
  • Easy to motorize

Applications:

  • Ophthalmology
  • Virtual reality headsets
  • LED illumination
  • Beam expanders
  • Education
