The 193nm laser beam expander is a crucial optical component used in laser systems. It is designed to expand and focus 193-nanometer ultraviolet (UV) laser beams, enabling them to propagate over larger distances or converge into smaller spots. This technology finds extensive applications in scientific research, industrial manufacturing, and medical fields.
Key Features:
Wavelength Adaptability: The 193nm laser beam expander is specifically designed to work with UV laser systems operating at a wavelength of 193 nanometers, making it indispensable for applications requiring this wavelength.
Beam Expansion and Collimation: One of the primary functions of the beam expander is to alter the diameter and propagation direction of the laser beam. Through proper design and shaping, it can either expand or collimate the laser beam to the desired size.
Industrial Applications: In industrial manufacturing, the 193nm laser beam expander is commonly used in processes such as microelectronics manufacturing, semiconductor device fabrication, precision cutting, and engraving. It helps to enhance production efficiency and product quality.
Scientific Research Applications: In the realm of scientific research, the 193nm laser beam expander is extensively employed in experiments across physics, chemistry, biology, and other disciplines. It facilitates exploration of the microcosm, analysis of molecular structures, and interactions, among other vital inquiries.

The BZ series of Zoom Variable Beam Expanders are available with 2X - 8X continuously variable beam expansion ratio. For the zoom models, the expansion ratio can be adjusted from the minimum to the maximum value via one full rotation of the zoom control. Once the desired magnification is obtained, a setscrew can be tightened to lock the magnification.
Our Zoom Variable Beam Expanders include the working wavelength 9.6um, CO2 10.6um, YAG 1064nm, 532nm, 355nm.
