Electrically focus-tunable lens

The EL-10-30 is the world’s first focus tunable lens that exhibits a diameter greater than 5 mm. By applying an electrical control voltage of 0-5V, the focal length of the lens can be rapidly tuned to a specific value in the range of 15mm to 100mm. This unique product allows you to design faster and more compact optical systems.
Applications for Optotune's fast electrically tunable lens are among others:

• Fast auto-focus
• Optical zoom
• NIR laser processing
• Illumination
• Laser shows
