Liquid Lenses by Optotune
In the ever-evolving field of machine vision, the ability to quickly and accurately focus on objects at varying heights and distances is crucial. Traditional methods often require multiple cameras or mechanical adjustments, leading to increased complexity and cost. However, Kowa Lenses, in collaboration with Optotune, offers a revolutionary solution: liquid lenses.
The Challenge
In many industrial applications, such as electronics inspection or bottle quality control, objects come in different sizes and heights, requiring precise focusing capabilities. Conventional fixed focal length lenses often fall short, needing manual adjustments or multiple cameras to achieve the desired focus, which can be time-consuming and costly.
The Solution: Liquid Lenses
Liquid lenses provide a cutting-edge solution by allowing rapid focus adjustment within milliseconds, all without mechanical movement. This technology is particularly effective in applications where objects of varying heights or working distances need to be inspected quickly and accurately.
How It Works:
As explained by Mark Ventura of Optotune, liquid lenses utilize a current-controlled system where the lens's shape is adjusted through a voice coil actuator. By increasing the current, the actuator pushes down on the lens, altering its shape and therefore the focus. This process can be controlled electronically, either manually via a computer interface or automatically using autofocus routines.
Application Examples
Integration with Kowa Lenses
Kowa’s collaboration with Optotune has led to the development of systems where liquid lenses are seamlessly integrated with Kowa’s high-quality optics. These customized designs place the liquid lens in the optimal position within the optical system, enhancing performance with lower f-numbers and superior image quality. The result is a versatile solution that meets the demands of various industrial applications, from microscopy to logistics.
The Impact
By integrating liquid lenses into machine vision systems, Kowa has significantly improved the efficiency and flexibility of these systems. The ability to adjust focus electronically within milliseconds not only reduces the need for multiple cameras but also enhances the accuracy and speed of inspections. This advancement has proven invaluable in industries requiring precise, high-speed imaging.
Conclusion
Liquid lenses represent a significant leap forward in optical technology, providing solutions that are both innovative and practical. By combining Optotune's liquid lens technology with Kowa's precision optics, we have created systems that offer unparalleled performance in demanding industrial environments. As the market for liquid lenses continues to grow, Kowa remains at the forefront, delivering cutting-edge solutions that meet the evolving needs of our customers.

Application Examples
- Electronics Inspection: In electronics manufacturing, components often vary in height. With a liquid lens integrated into the system, the camera can swiftly adjust focus from one component to another, ensuring sharp images across different focal planes. This eliminates the need for manual adjustments or multiple cameras, streamlining the inspection process.
- Bottle Inspection: For inspecting bottles of different sizes, especially in the neck area, liquid lenses offer the flexibility to focus at different depths without changing the camera's position. This capability is particularly beneficial in the quality control of plastic or glass bottles, where uniform inspection is critical.
- Medical Applications: In the medical field, inspecting liquids or detecting particles in fluid requires precise focusing at various depths. Liquid lenses enable scanning through different layers of a liquid or across a container, making it easier to identify contaminants or particles that might otherwise be missed.
