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:

Design faster and more compact optical systems without complex mechanics using the electrically focus tunable lens EL-10-30-C. By applying a current of 0 to 300mA, the focal length of the 10 mm aperture lens can be tuned to a specific value within milliseconds. The EL-10-30-C features threads on either side for easy mounting as well as the possibility to replace the cover glass with a fixed focus offset lens, allowing for free adjustment of the focal length range according to the requirements of your application.
The EL-10-30-C has two main optical configurations:
The basic configuration has planar cover glasses and a focal power range of 5 to 10 dpt, making this the best choice for macro imaging.
The “MV” configuration is optimized for the most common machine vision applications. It contains a negative offset lens so that the over all focal power range range goes from -1.5 to 3.5 dpt, making it the ideal choice for combinations with infinity corrected objective lenses.
Applications:
Building on customer feedback and learnings from over a decade, we are proud to present Optotune’s most effective liquid lens, the EL-12-30-TC. Redesigned from the ground up, it makes use of the latest materials and manufacturing technologies to provide best performance in a compact form-factor.
The tunable lens can be shaped from a flat zero-state into a plano-concave or plano-convex lens, resulting in a focal power range of -6 to +10 diopters (at -250 to +250mA).
The new lens design has been optimized for fast response times and low thermal sensitivity. Cover glasses are AR-coated for 420 to 950nm.
Key advantages:
Applications:
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.
Key advantages:
Applications:
| Dimensions (Ø x thickness) | 10 x 4 mm |
| Clear aperture | 3mm |
| Range of optical power (focal length) | -13 dpt (-77mm) to +13 dpt (+77mm) |
| Transmission wavelength (>94%) | 420 to 1600nm (VIS and NIR coating options) |
| Response time (10/90% step), settling time | 1, 4 ms |
| Wavefront error | <0.15/<0.15λ* |
| Operating temperature | -20 to 65°C |
* Wavefront error provided in λ RMS @525nm with optical axis vertical / horizontal
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.
