liquid focus Lenses

Liquid Focus lenses from Schneider-Kreuznach mark a step into the future of industrial lenses. Unlike conventional industrial lenses with motorised focusing, they are virtually wear-free, even after millions of cycles. Liquid Focus lenses offer a new level of flexibility for applications with fast changing working distances. Discover how Liquid Focus lenses can optimise your industrial applications.

What are liquid focus lenses?


Conventional lenses use mechanical elements to adjust the focus. In contrast, Liquid Focus lenses use a liquid lens element that changes its curvature by applying an electrical voltage to affect the focus. This allows for fast and continuous focusing. This process is almost wear-free and can be repeated almost indefinitely at very short intervals.

Benefits of liquid focus lenses


Liquid focus lens production

Liquid Focus lenses are the perfect choice for industrial applications where fast and precise focusing is critical. The stepless and fast focusing enables precise detection of objects with fast working distance changes. 


Applications for liquid focus lenses


Parcel sorting with a liquid focus lens

Liquid Focus lenses can be used in a wide range of industrial applications such as automation, inspection and metrology. They provide fast and precise focusing to capture and measure fine details of products like in logistics.
