  • Electronically Adjust Focus with Integrated Liquid Lens
  • Allows Magnification Adjustment without changing Working Distance
  • Overcomes Depth of Field Limitations

The Dynamic Focus VZM™ Lens utilizes an internal liquid lens to easily and seamlessly adjust focus over a 7X range, from 0.65X to 4.6X, while maintaining the zoom capabilities of the standard VZM™ Zoom Imaging Lenses. The lens also features a lockable iris, zoom control, and a rotatable mount that allows the camera to be properly oriented. Additionally, a removable mounting flange allows the lens to fit into the 50mm diameter thru hole of the rack and pinion mount #03-609. The liquid lens focus can be controlled via the ruggedized 6-pin Hirose connector and a USB port, while coarse magnification adjustments can be made manually. The software and driver (#88-940) allows the Dynamic Focus VZM™ Lens to be programmed to cycle through focus with a square, sinusoidal, or sawtooth waveform or adjustable frequency and focus-shift range.

These lenses won the Bronze Level 2015 Innovators Award.

Note: Optotune liquid lens driver #88-940 and hirose cable #88-941 (sold separately) are required for operation. For illumination purposes, it is recommended to use the 1.125” inner diameter fiber optic ring light (#54-175), which can connect to any of our fiber optic illuminators.
