WebBeam expanders are optical systems for increasing or decreasing the diameter of a laser beam. A beam expander can enlarge an input beam by the factor M, but it can also … WebBeam expanders are optical systems for increasing or decreasing the diameter of a laser beam. A beam expander can enlarge an input beam by the factor M, but it can also reduce it by the factor 1/M with a reversed optical beam path. Usually beam expanders are used to increase the diameter of laser beams.

Adjust the … WebBeam expanders are optical devices that take a collimated beam of light and expand its size (or, used in reverse, reduce its size). In laser physics they are used either as …
Weblaser beam with a beam expander. A beam expander consists of two lenses. First, the beam is diverged with a short focal length lens and then the diverging beam is re …
WebBeam expanders, commonly used in interferometry, remote sensing, laser materials processing and laser scanning applications, accept collimated light into the system and expand it into a larger collimated beam as its output.
WebMagnification Diopter correction function is provided, customer can fine-tune the collimated beam. Because it is a beam expander type of the Galilean, it is compact and has good aberration characteristics. Since the lens of zinc selenide has an anti-reflection coating, loss of light intensity is kept low.
