Telecentric lenses make precise measurements

Telecentric lenses add an extra level of precision to machine-vision systems.

In many machine-vision systems, such as those used in semiconductor inspection, precise repeatable measurements must be made consistently. To ensure this occurs, system developers must turn to more expensive optical systems based on telecentric lenses with which to image these parts. Many of the reasons for choosing telecentric lenses emerge from the limitations of more conventional lens systems.
