EL-10-42-OF data sheet - .PDF file.

Optotune’s new EL-10-42-OF lens — available from Pacer — has integrated optical feedback, measuring the optical power of the lens in real time. Optimal control is guaranteed in combination with the EL-E-OF-A electronics. As a result, reproducibility and focus stability are high, which makes the lens suitable for laser processing applications.

The working principle of the EL-10-42-OF lens with integrated optical feedback is based on the shape-changing flexible lens. The curvature of the lens is adjusted by applying an electrical current, and the focal length is accordingly tuned to a desired value within milliseconds.

The optical power of the lens increases with rising current. The working principle is based on Optotune’s well-established technology of electrically tunable lenses. The core that forms the lens contains an optical fluid, which is sealed off with an elastic polymer membrane. An electromagnetic actuator is used to exert pressure on the container and therefore changes the curvature of the lens. By changing the electrical current flowing through the coil of the actuator, the optical power of the lens is controlled.
