WebA typical application is to shape a deformed beam with a pair of plano-convex cylindrical lenses. A pair of positive plano-convex cylindrical lenses can be used to collimate and round the output of the laser diode. Another possible application is to focus the diverging beam onto the detector array with a single plano-convex cylindrical lens. WebCylindrical lenses are commonly used to manipulate laser beams, correcting asymmetric beams, generating light sheets or creating a single axis laser line. For example, two cylindrical lenses may be used in …
