Imaging systems are becoming ubiquitous in modern technology; camera-lens systems are almost everywhere you look. From smartphones to self-driving cars, our world is filled with computers that rely on machine vision to record, observe, and analyse their surroundings. The number of applications is continuously expanding and their needs are wide and varied. Due to the increasingly demanding performance requirements of these machine vision systems, there is almost always a need for more resolution. 

Integrating a single liquid lens into an imaging assembly can produce extremely flexible machine vision systems capable of rapidly changing their focus in milliseconds. Find out more about the different types of liquid lenses available and understand the benefits of liquid lens integration.

The Modulation Transfer Function (MTF) curve is an information-dense metric that reflects how a lens reproduces contrast as spatial frequency (resolution) varies. MTF curves can be used to compare the performance of multiple lenses and can help determine if an application is actually feasible with the respective lens.
