Abstract
A bi-acylindrical lens collimates a divergent elliptical laser beam. A first surface of the bi-acylindrical lens is shaped to form a first acylindrical lens, and a second surface of the bi-acylindrical lens is shaped to form a second acylindrical lens. The first acylindrical lens collimates the divergent elliptical laser beam on the fast axis, and the second acylindrical lens collimates the diverging elliptical laser beam on the slow axis.
