PTPR series

Projection patterns for machine vision

Catalog 2019

Opto Engineering supplies a comprehensive range of projection patterns compatible with our LED pattern projectors.
PT projection patterns can be either laser-engraved, with 50 µm geometrical accuracy, or photolitography-engraved for more demanding applications (2 µm accuracy).

Custom geometry patterns can also be provided upon request.

Pattern engraving process

Projection accuracy depends both on the pattern manufacturing accuracy and lens distortion.

The edge sharpness of the projected pattern depends on both the lens resolution and the engraving technique: laser-engraved patterns (part numbers ending with a L) or photolitography-engraved patterns (part numbers ending with a P) can be chosen depending on the type of the application
