Optotune Focus Tunable Lens EL-10-30-C and EL-10-30-Ci

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 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 two main optical configurations:

  1. The basic configuration has planar cover glasses and a focal power range of 5 to 10 dpt, making this the best choice for macro imaging.

  2. The “MV” configuration is optimized for the most common machine vision applications. It contains a negative offset lens so that the over all focal power range range goes from -1.5 to 3.5 dpt, making it the ideal choice for combinations with infinity corrected objective lenses.

Applications:

  • Machine vision
  • Microscopy
  • Biometric systems
  • Metrology
