Product Info
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
ML-20-37-VIS-36D
Applications
Optotune's ML-20-37 is the ideal choice for:
Virtual reality headsets
LED illumination
Beam expanders
Education
ML-20-37-VIS-36D-C
