|Fast electrically tunable lens EL-10-30|
Design faster and more compact optical systems without complex mechanics using the electrically focus tunable lens EL-10-30. By applying a current of 0 to 300mA, the focal length of the lens can be tuned to a specific value in the range of 20mm to 120mm within milliseconds. By choosing among two optical fluids and several coating options for the cover glasses, the EL-10-30 can be adjusted to your needs. The new C-mount version EL-10-30-C also 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.
Applications for Optotune's EL-10-30 are among others:
