EL-12-30-TC
Building on customer feedback and learnings from over a decade, we are proud to present Optotune’s most effective liquid lens, the EL-12-30-TC. Redesigned from the ground up, it makes use of the latest materials and manufacturing technologies to provide best performance in a compact form-factor.
The tunable lens can be shaped from a flat zero-state into a plano-concave or plano-convex lens, resulting in a focal power range of -6 to +10 diopters (at -250 to +250mA).
The new lens design has been optimized for fast response times and low thermal sensitivity. Cover glasses are AR-coated for 420 to 950nm.
Key advantages:
Slim housing that adds only 5.8mm in optical axis
Fast rise & settling times of 3ms & 10ms
Low temperature sensitivity <0.01dpt/°C
Low power consumption of 55mW for a 5 diopter range
