Beam Expander By Wuhan Carman Haas Laser Technology Co.,ltd

Our company is amongst well known companies that manufacture, supply, trade and exports an extensive range of Beam Expander. Beam expander is a kind of optical system is composed of two or more elements, it has a variety of purposes: first the extension of beam, then the focus can get smaller. Beam expander can improve beam collimation characteristics.

Mainly used for marking, engraving, drilling, and other fields.
