WebIn general, a beam shaper (or beam converter) is an optical device which somehow reshapes a light beam, i.e., it modifies its spatial profile. For example, there are refractive and micro-optic beam shapers which … WebHolo/Or's Vortex DOE converts a collimated single mode (TEM00) Gaussian beam to TEM01 axisymmetric mode. By enlarging the incident beam, the emission spot can be further cured. If the beam divergence angle is small (1º or less), the output quality is not significantly affected and an accurate working distance is required.
