Liquid lenses are often used in ophthalmology, where refraction control and depth of field adjustment is crucial. Liquid lenses can be easily integrated into tube lenses or in infinity A liquid lens can quickly and precisely focus to various object planes, therefore speeding up focus stacking. Focus stacking is often required when imaging with high magnification objectives due to their limited depths of field. Liquid lenses improve and simplify the process of focus stacking (“z-stacking”) in microscopy imaging applications.

A liquid lens, free of mechanical translation, overcomes these speed and depth of field limitations by refocusing to different heights in the matter of milliseconds. A standard imaging lens requires mechanical refocusing per every object, causing a delay that can limit high-throughput. In a standard inspection system, objects of different heights are imaged as they pass by on a fast-moving conveyor belt. This is Section 7.3 of the Imaging Resource Guide.įigure 2: This animation illustrates the advantages of implementing a liquid lens into a machine vision imaging system for inspection. Typical mechanical lenses are capable of ~100,000 cycles, whereas a liquid lens can withstand approximately ~50,000,000 cycles (Berge, 2013). Liquid lenses can be used in conjunction with many accessories, such as filters and apertures, which are required by many high-speed applications, such as distance sensors or controllers. Complexity of Integrationĭepending on available equipment and the application, liquid lenses can be difficult to integrate. By eliminating the moving parts and mechanical adjustments typically found in fixed focal length and zoom lenses, the focusing process is quicker. Liquid lenses are designed to operate across a very wide range of optical powers (focal lengths) at high speeds. Liquid lenses embedded inside systems do not reduce sensor coverage. The small apertures restrict liquid lenses and only allow for use with sensors up to about 1/1.8” if the lens is retrofitted onto the front of an existing machine vision lens. Liquid lenses are limited by their small aperture sizes - the largest is approximately 16mm in diameter.

By removing those lenses and replacing them with a small liquid cell, the overall size and weight of the full lens is reduced. In addition, liquid lenses are comparable in functionality to many individual lenses within an assembly. Mechanics are eliminated in a liquid lens which enables their compact design. Liquid lenses can be implemented in various locations throughout an imaging system, such as being embedded within or threaded to the front or rear of an imaging lens.

Fixed Focal Length and Zoom lenses often rely on mechanical or manual adjustments to change focus, which can slow the imaging system. Liquid lenses have very fast response times, are electrically tunable via voltage or current, and respond in a matter of milliseconds.
