电动调焦镜片

  • · 型 号:EL-10-30-Ci

产品概述

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 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.

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 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.

The EL-10-30-C has three main optical configurations:

  1. The basic configuration has planar cover glasses and a focal tuning range of 200mm down to 80mm, making this the best choice for macro imaging.
  2. The "MV" configuration is optimized for the machine vision market. It contains a negative offset lens so that the over all focal tuning range goes from slightly negative down to 170mm, making this the ideal choice for combinations with infinity corrected fixed-focus lenses.
  3. The "LP" configuration is optimized for the laser processing market and comes with high-power 1064nm coated fused silica cover glasses. The smaller tuning range due to a stiffer membrane allows for a minimal wavefront error, which allows to work with small spot sizes.

The following table summarizes the main specifications of the EL-10-30-C series:

 *All the above models are available with a 6-pin FPC connector (OEM version) or with a 6-pin Hirose connector (industrial version)

 A new feature added in April 2014 is calibration data saved directly on the lens, which allows for more precise open loop control including temperature compensation.
