galilean beam expander
The Galilean beam expander is an optical device designed to increase the diameter of a laser beam while maintaining its divergence angle. Its main functions include beam enlargement, which is crucial for a variety of technical applications, and the preservation of the beam's quality and shape. Technological features of the Galilean beam expander encompass a simple yet effective design composed of a positive lens and a negative lens, which work in tandem to expand the beam. This device is widely used in laser technology, where precise control over the beam's characteristics is essential. Applications range from laser cutting and welding to medical procedures and research, making it an indispensable tool in the respective fields.
