With a clear aperture of 16mm Optotune presents the world‘s largest electrically focus tunable lens bringing fast and reliable focus control to high end applications.
Based on the well-established shape-changing lens technology, the EL-16-40-TC can be shaped from a flat zero-state into a plano-concave or plano-convex lens, resulting in a focal tuning range of up to -10 to +10 diopters (at -250 to +250mA).
Response & settling times are 5 & 25ms, respectively, which is magnitudes faster than most mechanical alternatives. Thanks to the robust VCM actuated design the lens can run at high frequencies and performs reliably over billions of cycles.
The design was optimized to minimize thermal drift effects to as little as 0.02 dpt/°C and with the built in temperature sensor, an overall reproducibility of typically +/- 0.05 diopters is achievable.

The electrically focus-tunable lens EL-10-42-OF with integrated proprietary optical feedback (OF) is dedicated to 2.5D and 3D laser applications. It sets the highest standards in terms of spot quality and speed.
With a focus tuning range of -2.0 to +2.0 diopters, a constant laser spot can be controlled over a large range along the z-axis (up to 250mm), with a long term repeatability of <0,02 dpt.
The EL-10-42-OF comes in two versions, one designed for use in the NIR (950-1100nm) up to 50 W, the other for the visible (532 nm) up to 20 W.
Applications:
| Dimension | 47 x 42 x 41 mm |
| Weight | 90 g |
| Maximum laser power | 50 W (NIR), 20 W (green) |
| Maximum input beam diameter | 8 mm |
| Response time (10-90%) | 8 ms |
| Processing speed | 6 m/s (with digital controller) |
| Laser spot diameter | < 45 μm (constant) |
| Z-range* | 70-100 mm |
| Field size* | 100 x 100 mm |
| Repeatability* | < 500 μm |
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.

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:
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:
