A Revolutionary Liquid Lens Solution in Collaboration with Optotune
Liquid Lenses by Optotune: Revolutionizing Machine Vision
In the rapidly advancing field of machine vision, the ability to quickly and accurately focus on objects at varying heights and distances is critical. Conventional methods often rely on multiple cameras or mechanical adjustments, adding complexity and cost to the system. However, Kowa Lenses, in collaboration with Optotune, offers an innovative alternative: liquid lenses.
The Challenge: Precision Focus in Dynamic Environments
Industrial applications such as electronics inspection or bottle quality control present unique challenges, as objects often vary in size and height, requiring precise focusing capabilities. Traditional fixed focal length lenses frequently fall short, necessitating manual adjustments or multiple cameras to achieve the required focus. This process can be time-consuming, complex, and expensive.
The Solution: Harnessing Liquid Lens Technology
Liquid lenses provide a groundbreaking solution by enabling rapid focus adjustments in just milliseconds, all without mechanical movement. This technology is especially effective in scenarios where objects of different heights or varying working distances need to be inspected quickly and with high precision.
How Liquid Lenses Work
Mark Ventura from Optotune explains that liquid lenses utilize a current-controlled system, adjusting the lens shape through a voice coil actuator. As current is increased, the actuator applies pressure to the lens, altering its curvature and, consequently, its focus. This process can be managed electronically, either through a manual computer interface or via automatic autofocus routines, making it adaptable to various applications.
Application Examples of Liquid Lenses
Electronics Inspection: In electronics manufacturing, components often vary in height. By integrating a liquid lens into the inspection system, the camera can rapidly shift focus from one component to another, capturing sharp images across different focal planes. This eliminates the need for manual adjustments or multiple cameras, streamlining the inspection process and enhancing efficiency.
Bottle Inspection: During bottle quality control, inspecting bottles of varying sizes, especially around the neck area, demands flexible focus capabilities. Liquid lenses enable the camera to adjust focus at different depths without changing its position, making them ideal for ensuring consistent quality control of plastic or glass bottles.
Medical Applications: Liquid lenses also excel in the medical field, where precise focusing at various depths is essential for tasks like inspecting liquids or detecting particles in fluids. By allowing the camera to scan through different layers of a liquid or container, liquid lenses help identify contaminants or particles that might otherwise go unnoticed.
Seamless Integration with Kowa Lenses
The collaboration between Kowa and Optotune has resulted in 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.
