Beam shaping is well known in material processing. The normal Gaussian beam profile may be is converted to a top hat (flat top) to more efficiently utilize the full energy of the beam. The same beam shaping optics can also…
Congratulations to Elizabeth Hillman, associate professor of biomedical engineering at Columbia Engineering, who implemented a high speed polygon scanner in a new 3D microscopy technology. SCAPE (swept confocally aligned planar excitation microscopy) uses a simple, single-objective lens imaging geometry that…
A suitable beam expander is used to adapt the source to the optical system. In an R&D project, multiple sources may be tested. Each source may have a different beam diameter so it is easier to use a zoom expander…
The high speed and high laser damage threshold of polygon scanners are required for many high power and Ultrafast / Ultra Short Pulse (USP) material processing applications. With pulse lasers operating at MHz rates, traditional galvanometer scanners are not fast…
