Liquid Lenses
Corning® Varioptic® Variable Focus Liquid Lenses
• Vary Focal Length by Applied Voltage
• Ideal for Machine Vision Autofocus Applications
• Less Power Required than Traditional Autofocus Lenses
Corning® Varioptic® Variable Focus Liquid Lenses consist of a conductive liquid deposited on a flat, conductive
substrate. Applying a voltage between the substrate and the liquid causes an insulated material within the
liquid to change shape, yielding a variable focal length. These lenses are designed with a stable optical axis,
can operate regardless of orientation, and feature AR Coatings optimized for excellent transmission between
400 and 700nm. Corning® Varioptic® Variable Focus Liquid Lenses are ideal for autofocus applications, and
with no moving parts, they are faster, more durable, and consume less power than traditionally actuated
autofocus lenses. A 2.5mm aperture lens for high speed applications and a 3.9mm aperture lens for long focal
lengths, large sensor size, and laser applications are offered. The lenses are also available in development kits
which include lenses, drive electronics, cables, and software for easy use and integration.

PixeLINK® USB 3.0 Autofocus Liquid Lens Cameras
provide the ability to seamlessly integrate and control
liquid lenses. By enabling the liquid lens to be directly
connected to the camera, it allows for fast, continuous
focus control. This simple autofocus system makes
these cameras ideal for high speed applications such
as bar code reading, inspection, and biomedical applications.
PixeLINK® USB 3.0 Autofocus Liquid Lens
Cameras are compatible with our TECHSPEC® Cx Series
Fixed Focal Length Lenses, which combine high
resolution image performance with built-in liquid lens
integration. Note: Liquid lens is not included.
