Integrated liquid lenses in machine vision

This article is brought to you by: 

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.

Modulation Transfer Function (MTF)

This article is brought to you by: 

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.
