ULO Optics Post Objective Scanner Lenses

Singlet, doublet, triplet and telecentric scanner lenses are all used in the ‘pre-objective’ scanning configuration. However, there is a second arrangement called ‘post-objective’ (or ‘3-axis’) where the scanning mirrors follow the focusing optics. The small first lens is also translated in synchronisation with the mirrors to keep the correct focus on the image surface. Unlike the pre-objective arrangement, the same set of optics can usually cope with more than one field size.

Applications for these lenses typically are three-dimensional applications where the working distance gets varied on the fly, such as remote welding.

ULO Optics designs and manufactures these post-objective lens sets to your requirements.
