Doe beam shaping

WebDOE expander. Holo/Or has developed a module that changes the output parameters of the diffractive optical element (DOE).This module reduces or magnifies the entire angle of the DOE's output at some magnification. Unlike common beam expanders, it takes into account the characteristics of Holo/Or's beam shaping, beam splitting, and beam fock ... WebBeam shaping is the process of redistributing the irradiance and phase of a beam of optical radiation (LBSA, 2006). There is no single beam shaping method that addresses all …
