Optotune EL-16-40-TC

EL-16-40-TC

With a clear aperture of 16mm Optotune presents the world‘s largest electrically focus tunable lens bringing fast and reliable focus control to high end applications.

Based on the well-established shape-changing lens technology, the EL-16-40-TC can be shaped from a flat zero-state into a plano-concave or plano-convex lens, resulting in a focal tuning range of up to -10 to +10 diopters (at -250 to +250mA).

Response & settling times are 5 & 25ms, respectively, which is magnitudes faster than most mechanical alternatives. Thanks to the robust VCM actuated design the lens can run at high frequencies and performs reliably over billions of cycles.

The design was optimized to minimize thermal drift effects to as little as 0.02 dpt/°C and with the built in temperature sensor, an overall reproducibility of typically +/- 0.05 diopters is achievable.

Key advantages:

Large clear aperture of 16mm

Fast response time of 5ms

High repeatability of typically +/- 0.05 dpt

Features

Configurations

The EL-16-40-TC is available in its compact form for OEM integration but also with multiple thread adapters and a robust Hirose connector for industrial use, where the tunable lens can be easily combined with off-the-shelf imaging lenses.

Two different membrane configurations allow for a focal power range of 5 and 20 dpt, respectively, and cover glasses are available for VIS & NIR coatings.
