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.
