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.

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.

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.
Key advantages:
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:
Design faster and more compact optical systems without complex mechanics using the electrically focus tunable lens EL-10-30-TC. By applying a current, the focal length of the 10 mm aperture lens can be tuned to a specific value in milliseconds. Thanks to an integrated temperature sensor and characterization data, the lens can be driven to precise focal powers using Optotune’s lens driver 4. The EL-10-30-TC is available with two broadband coating options, VIS for 400-700nm and NIR for 700-1100nm.
