EL-10-30
Zoom

It is the lens that is tunable from 45mm to 120mm focal length by an electrical control.
It enables to change the shape of the lens by which is sealed with an elastic polymer film is filled with an optical fluid, and pressure is applied by an electromagnetic actuator.
It can be varied at high speed curvature of the lens. Zoom optical system, auto focus, lighting system and so on are able to build a system more compact optical systems.

◦By flexibility and taking advantage of the optical film having a high transmittance, both the variable function of the curvature of the lens and the characteristics of the optical lens had achieved.
◦We offer two types of near-infrared and visible type.

▶It is also available to provide other than products in the catalog such as focal length or aperture size. Please contact our sales division.

Attention

▶The focal length and the applied current is not proportional, therefore it is necessary to make the calibration of the lens control of the open loop.
