The compact EL-3-10 lens is designed for OEM integration into optical systems for various applications. The working principle is based on the well-established shape-changing lens technology. The curvature of the lens is adjusted by applying an electrical current. Thereby, the focal length is tuned to a desired value within very few milliseconds. The lens architecture is “push pull” which means that the lens curvature is deflected from concave to convex. With actuators based on proven voice-coil technology, the EL-3-10 focus tunable lens is extremely reliable and robust, well suited even for applications in harsh environments over large temperature ranges.

Optotune has co-designed with its optics partners a series of lens modules developed around its electrically tunable lenses. This results in an optically optimized and integrated solution that simplifies the design of the vision system.
The ELM-F series consists of fixed focal length lenses specifically designed to accommodate Optotune’s electrically tunable lenses in the optical path. The series, which is in continuous expansion, currently supports S-mount and C-mount cameras up to a sensor size of 1.1” with focal lengths ranging from 5 to 300mm.
As a result of the optimization process, customers can benefit from:
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.
