Advanced optical system design

The design and production of an fil aspheric focussing lens for a high powered laser system operating at 1054 nm is described- The degree of flexibility in the choice of parameters in the lens is commented upon These parameters are chosen carefully, an extramely versatile lens capable of a large vavelength cover is produced: its manufacture is also considerably easied On this latter point, a comparison is made between the manufacture of its aspheric surface by high quality, although conventional, optical manufacturing practices, with an asphoric generated and polished entirely by a CNC jig grinding machine.
