Corning® Varioptic® Lenses rely on the electrowetting principle where the interface of two liquids is modified when a voltage is applied. This eliminates moving parts, bringing a unique competitive advantage to the market, and enabling fast focus.

 

Varioptic liquid lenses are ideal to offer a fast focus change, with no moving mechanical parts, highly improving shock resistance and life span, without degrading performance in high vibrations environments.

CORNING VARIOPTIC Technology Guide
 

 

Corning Varioptic liquid lenses are ideal to offer a fast focus change, with no moving mechanical parts, highly improving shock resistance and life span, without degrading performance in high vibrations environments.

 

Outstanding quality from digital pictures comes from a precise control of the focus: a good picture requires the main subject to be very sharp, and the rest of the picture more blurred. An effective AF capability is thus essential to obtain a superior photo. Varioptic’s liquid lens technology delivers fast, continuous and precise focus control. This is for use in all situations where the digital capture is critical:

 

  • digital photography

  • industrial data capture

  • barcode reading (1D and 2D)

  • biometric data acquisition

  • videos with large amplitudes of object distance variations

 

In the drawing below, Electrowetting is explained in a very basic configuration: a drop of oil is deposited on a planar surface , made of a flat electrode covered with a thin insulating and hydrophobic layer, all this being immersed in a water based conducting liquid. Voltage is applied between the flat substrate electrode and another electrode dipped in the conducting liquid (not shown on the photographs).

 

 

 

 

 

 

 

 

 

Variable Auto Focus Lense

 

The ARCTIC 316 liquid lens is dedicated to applications requiring fast response time and high optical power. It is especially suited to industrial applications.

 

 

ARCTIC 39N0 is designed specifically for variable focus products needing a larger clear aperture than Arctic 316's: long focal objectives, large sensors, C-Mount objective lenses, laser beam shaping.

 

 

Auto Focus Lense Module

 

The Caspian series is a family of auto focus lens modules that combine a fix focus objective, a liquid lens and a flex cable into a standard mount barrel. Caspian modules are designed for fast and easy integration to standard camera boards.

Varioptic liquid lenses are ideal to offer a fast focus change, with no moving mechanical parts, highly improving shock resistance and life span, without degrading performance in high vibrations environments.

 

Based on electro wetting liquid lens technology, the new Caspian C-39N0-16 objective specifically designed for Machine Vision applications, compatible with 2/3’’ sensors, enables high-speed, noiseless and electronically controllable auto-focus from 10cm to infinity.

 

Easy to use, the Caspian C-39-N0 includes all electronic components to drive the liquid lens and just needs a DC power supply. Focus can be controlled through RS232, I²C, Analog or SPI inputs.

 

No wear, high speed, shock resistance, low power consumption, noiseless : with these key advantages, the Caspian C-39N0-16 objective, based on liquid lens technology from Varioptic can be seamlessly integrated on any industrial cameras.
