Gardasoft introduces industrial lens controller for Optotune focus-tunable lenses

TR-CL Series single channel industrial lens controllers from Gardasoft—a recipient of a gold-level award in the 2016 Innovators Awards—provide accurate and repeatable control of Optotune EL-10-30 and EL-16-40 focus-tunable lenses.

These GigE Vision compliant lens controllers allow focus-tunable lenses to be used as part of Gardasoft’s Triniti machine vision platform. In this way, access and control of system cameras, lighting, and lenses is possible in a single machine vision environment using conventional image processing software or via a Triniti software development kit, according to a press release.

Optotune’s focus-tunable lenses allow the focus to be adjusted by changing the shape of the fluid-filled lenses electrically, which enables quick and reliable focus adjustment for machine vision applications requiring imaging of objects with varying height. The TR-CL Series of lens controllers delivers focus change as fast as 1ms for dynamic lens control in applications including postal inspection, ophthalmology, microscopy and the life sciences.

The lens controller has three modes of operation: single configurable optical power; two optical powers selected by a digital input or optical power set by an analog input. Additionally, the controllers include constant current lens drive and lens EEPROM data communications. Data can be automatically read from an EEPROM inside the lens to calibrate the controller response and the performance of the controller is automatically tailored to each individual lens. The TR-CL series delivers -400mA to +400mA in 0.1mA steps.

A National Instruments LabVIEW utility is available for the controllers, as well as utilities for other leading machine vision imaging software packages, including Cognex VisionPro, Teledyne DALSA’s Sherlock, and Stemmer Imaging’s CVB.
