Geomatec is pleased
to introduce two lines of high quality optical assemblies to the most
demanding scanning applications. These product lines include beam
expanding telescopes and f-theta and telecentric scanning lenses. Please click the buttons above
or the following links to access these product pages.
Expanders are critical elements of scanning
systems. This element is often located at or near the raw output of a
high power laser. Its entry surfaces must be precise and must survive
high output power from the laser. The function of the beam expander is
to then expand and collimate this beam prior to its introduction to a
scanning system and focusing lens. The focusing lens is most often
located after a galvanometer or other scanner based assembly. Beam
Expanders are designed and produced in fixed and variable models.
The greater the degree to which the beam is expanded before introduction to
the scan lens, the smaller a spot may be produced by that beam at the work.

Lenses are used in scanning systems to vary the focal
length of the output beam to create a flat plane from all possible output
positions of the scanning system. Without such a lens, the various
output positions of the scanning system would describe a portion of a
sphere. Scanning lenses are
designed and produced in f-theta and telecentric types.
