Product Family Description

• Vary Focal Length by Applied Voltage
• Ideal for Machine Vision Autofocus Applications
• Less Power Required than Traditional Autofocus Lenses
• Development Kits and Lenses with Thermistor Available

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. The 1.6mm aperture lens is the smallest liquid lens currently available and specifically designed for ultra-compact cameras, such as barcode engines, industrial and medical endoscopes. 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 also offered, as well as the largest available 5.8mm clear aperture lens that has been designed for machine vision applications with long focal distance objectives, large sensors, or C-Mount objective lenses. The lenses are also available in development kits which include lenses, drive electronics, cables, and software for easy use and integration via USB-A connection. Versions with thermistor (temperature-dependent resistors) for temperature sensitive applications are also available.

Note: These products are sensitive to electrostatic discharge (ESD). Handling precautions should be taken to prevent accidental damage, such as using anti-static devices and storing products in static-safe containers when not in use.
