Beam Expander - High Power CO2 Laser
The most common type beam expander is derived from Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam focus at the output. For low expansion ratio, the Galilean telescope is most often employed due to simplicity, small package size and low cost. Beam expander is commonly used to magnify the laser diameter to be focused back in smaller spot size.
CO2 BEX - UniBET Series
UniBET series Beam expander is developed for higher power CO2 laser >100w without water cool. With consistence in outer dimension and connecting thread M30x1, UniBET series provide customer convenience and wide range of fixed magnification of 1.5x-10x.
