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.

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:
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:
Applications:
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 |

| Laser spot diameter | < 45 μm (constant) |
| Z-range* | 70-100 mm |
| Field size* | 100 x 100 mm |
| Repeatability* | < 500 μm |
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.
