Description: 

A laser beam expander is designed to increase the diameter of a collimated input beam to a larger collimated output beam. Beam expanders are used in applications such as laser scanning, interferometry, and remote sensing. Contemporary laser beam expander designs are a focal systems that developed from well-established optical telescope fundamentals. In such systems, the object rays, located at infinity, enter parallel to the optical axis of the internal optics and exit parallel to them as well. This means that there is no focal length to the entire system.

Designed for use with CO2 Lasers, these Adjustable Beam Expanders offer precise collimation of output beams in a compact, Galilean design. By adjusting the distance between the two ZnSe lenses via the focus ring, the user is able to compensate for slightly convergent or divergent entrance beams. All CO2 Adjustable Laser Beam Expanders have antireflective coatings on every lens surface. AR coating transmits >99% of optimum wavelength (10.6μm).
