Motorized beam expander

March 1, 1997

A motorized beam expander is continuously adjustable from 2X to 8X magnification and is designed for use at 1064 nm. The expander can accept an entrance beam 4 mm in diameter and provides an exit beam with diameter u¥to 31 mm. The zoom and focus are adjustable by stepper motors controlled remotely using software running on a PC under Windows 3.1, 3.11, or 95.
