Fast Electrically Tunable Lens EL-10-30-C

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 two main optical configurations:

1. The basic configuration has planar cover glasses and a focal tuning range of 200mm down to 100mm, 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 286mm, making this the ideal choice for combinations with infinity corrected fixed-focus lenses.

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

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

** Wavefront error provided in λ RMS @525nm with optical axis vertical / horizontal
