Swiss optical dark horse Optotune, liquid lens changes industrial imaging

In traditional optical systems, focusing usually relies on mechanical structures to push the lens to move, which not only has slow response speed, but also has many limitations: focusing depends on the distance of the object, the motor system leads to a large and complex overall structure, high maintenance and calibration costs, and lifespan issues caused by mechanical wear.

Optotune has broken through these bottlenecks with its independently developed adjustable focus liquid lens technology. Without the need for mechanical movement, fast and precise focus adjustment can be achieved, providing a solution for various application scenarios that require high-speed focusing.

Compared with traditional optical solutions, Optotune's liquid lenses not only eliminate mechanical movement structures, but also achieve a leapfrog improvement in performance:

Focusing speed can reach millisecond level, meeting the requirements of high-speed dynamic scenes;

• Compact and sturdy structure, suitable for various complex environments;

• With a lifespan of over 1 billion cycles, far exceeding the reliability of traditional systems;

Simultaneously cost-effective, suitable for large-scale integrated applications.

As a result, Optotune's adjustable focus lenses have been widely used in various fields such as industrial automation, medical imaging, and smart consumer electronics, becoming the core optical components driving the implementation of cutting-edge technologies.

1. Working principle

The working principle of Optotune adjustable focus liquid lens can be simply understood as "using liquid to deform the lens", thereby changing the focusing state. Its core structure is a small container containing transparent optical liquid, covered with a very thin but elastic plastic film. Every time we need to change the focal length, the voice coil motor pushes the liquid towards the middle of the diaphragm, causing it to bulge or sink. This change will cause the shape of the lens to change from "concave" to "convex" or remain "flat", just like the human eye adjusts the lens, thereby allowing the focusing ability of the lens to change in real time. There are no mechanically moving parts in the entire process, resulting in faster speed, longer lifespan, and more compact structure. In addition, this lens can be precisely controlled by current, and we have also performed gravity compensation on all models to ensure stable and repeatable focusing every time, making it suitable for industrial and medical scenarios that require high precision.

2. Optotune liquid zoom lens

This lens has multiple models that can meet the needs of different focal lengths and wavelengths (400-2500nm). Not only is it compact in design, but it also comes with flexible printed circuit connection wires for easy installation into optical systems. There are also models specially designed for industrial customers, equipped with specialized installation threads and Hirose connectors to ensure stable and reliable equipment.

Product advantages:

1. Fast response speed:Response time only takes a few milliseconds

2. Low dispersion:Abbe# V>100

3. No mechanical wear and tear:Liquid optical devices have a lifespan of over 1 billion cycles

4. High repeatability:＜0.1 d pt

The maturity of this liquid lens imaging technology stems from an extraordinary idea. When Optotune was founded in 2008, it recognized that the human eye has the ability to automatically adjust focal length. Based on this, Optotune developed a liquid focusing lens in 2010, ushering in a new era of liquid zoom lenses. As of today, Optotune has a network of 28 sales partners and distributors located in 30 different countries. The company continues to drive technological progress through multiple innovative products. Optotune's success is attributed to its long-term commitment to the concept of win-win cooperation. Over the past few decades, Optotune has established close partnerships with multiple lens manufacturers, including Edmund Optics, Linghou, Opto Engineering, and Schneider. Through this collaboration, both parties have jointly developed a variety of integrated lens products suitable for different application scenarios.

3. Integrated lens - ELM-F series

The ELM-F series is an integrated lens developed in collaboration between Optotune and lens manufacturers. It consists of fixed focal length lenses specifically designed to accommodate Optotune's electrically tuned lenses in the optical path. This series continues to expand, currently supporting S-mount and C-mount cameras, with the largest sensor size of 1.1 inches and a focal length range from 5 millimeters to 300 millimeters.

Product advantages:

1. Verify through testing:This module has undergone comprehensive testing and integration

2. No dark corners:Low f value, very clear range

3. Compact design:Optical systems that can be used for various narrow working distances
