Focus-tunable lenses are special optical lenses that can adjust their focus through electrical or mechanical means. Unlike traditional fixed-focus lenses, these lenses can change their focal length, playing a crucial role in various optical applications. For more details, please visit the official website of Edmund Optics via the link below.
A lineup of three product groups featuring electrically adjustable and manually adjustable focus-tunable lenses.
Focus tunable lenses, known as liquid lenses, have distinct advantages over traditional optical devices. We offer the electric EL series and the modular ELM series. ● Compact design ● High-speed response ● High reliability ● Robust ● Low sensitivity to tolerances ✤ Customization is available. *You can download the PDF catalog. Please contact us for more details.*
Continuous focus adjustment is possible; to replace the functions of the completed lens kit; the focal length range is +50 to +120mm.
The electronic Optotune focus-tunable lens provides a single lens solution for focusing and zooming purposes. By applying a control current, a small plano-convex lens changes its curvature. The electronically controllable focal length range is +50 to +120 mm, making it suitable for various applications. This eliminates the need for a system composed of multiple lenses. There are two models available: the VIS coat model with an anti-reflective coating for the visible range and the NIR coat model with an anti-reflective coating for the near-infrared range.

Continuous focus adjustment is possible; equipped with C-mount screw-in and lens offset functions to facilitate system integration.
The Optotune C-Mount Focus Tunable Lens facilitates mechanical integration in imaging systems by combining Optotune's electronic focus tunable lens with a C-mount compatible housing. By applying a control voltage to the lens via a Hirose connector, the Optotune C-Mount Focus Tunable Lens can adjust the focal length range from +80 to +200mm. Its ability to adjust the focal length makes it ideal for replacing focus adjustments and zoom systems that use multiple lenses. When shifting the focal length range, please use a plano-convex or plano-concave lens with a diameter of 12mm (with a thickness of less than 4.7mm) as an offset lens.
