Telecentric lens

Telecentric Lens is designed to prevent errors from perspective. There are no size variations when a subject is in depth of focus (DOF). For this reason, Telecentric Lens is used in high-precision measuring applications such as Machine Vision and Metrology.

Our Telecentric lenses are various in working distance and magnification applying to various type of sensors. We design and produce Telecentric lenses at the specific request of the customer.

This lens is mostly used in alignment mark inspection and measurement.
