Edmund optics offers laser beam shaping solutions to collimate laser beams transform beam profiles convert beam shapes and much more.
Top hat shapers are either refractive or diffractive optics.
Tophat beams are often used in industry for example for laser drilling of holes in printed circuit boards.
Tem 00 or multimode with gaussian or similar intensity profile can be applied.
Conventional diffractive beam shaper requires accurate alignment and beam control.
π shaper transforms gaussian or similar intensity distribution of source laser beam to a flat top one.
Their optical design makes holography microscopy and system integration suitable especially over great distances.
A flat top beam or top hat beam is a light beam often a transformed laser beam having an intensity profile which is flat over most of the covered area.
Multi year developments are realized in family of pishaper systems 70 models.
The refractive adloptica πshaper flat top beam shapers create a collimated flat top beam and feature near 100 efficiency with no internal focusing allowing for high power input beams figure 4 and figure 5.
A flat top laser beam shaper is a diffractive optical element doe that transforms the gaussian beam into a flat top beam with uniform intensity inside a well defined shape with pre designed angular dimensions and a.
Adloptica works in field of multifocus and laser beam shaping optics finding numerous industrial and scientific applications.
A top hat beam shape r also known as flat top beam shaper is the high end option applicable for laser systems that use single mode low m 2 laser beams typically m 2 1 5.
They are also used in very high power laser systems which use chains of optical amplifiers to produce an intense beam.
