Request InfoEdmund Optics Inc.Edmund Optics Inc. has introduced two liquid-filled lenses from Optotune Inc. The tunable polymer electrically and manually focused lenses replace multiple optical elements, including a lens kit, eliminating the complex alignment and optomechanical issues associated with multilens systems. The electrically focused models provide a single-lens solution for focus and zoom objectives. When the user applies a voltage to each compact planoconvex lens, the lens changes effective focal length. Each lens is filled with an optical liquid, and the change in voltage alters the pressure profile of the...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/26/2022Optical MountsThe E-Series of Adjustable Size Kinematic Optical Mounts from Edmund Optics Inc. can be used for mounting a wide range of round, rectangular, and square optical components, including round and...Photonics.com 4/5/2024Ruggedized LensesThe 1.4-in., 45-MP MPT-R Series and 1-in., 20-MP MPZ-R Series (shown) from Computar® are 45-MP and 20-MP ruggedized lenses for harsh environments.
