Contents Optical Part Design » Optical Surface » Optical Surface Parameters » BeamPrint page Beam This section provides information on the beam types available when designing an optical surface. This section contains the following topics:RadiiThe Radii beam type allows you to create spherical facets that ideally diffuse light.FluteFlutes are shaped by the geometrical angle between tangents of the support.FreeformWith the Freeform beam type, elements are shaped by specifying the rectangular area where the light should be sent in.Sharp CutoffThe following section focuses on Sharp Cutoff beam type. A Sharp Cutoff beam directs light in a certain way so that it remains under a defined line. « TargetRadii »
