Wavelength photoelectric laser marking welding cutting beam expander fixed magnification 1.5~ 15 times 355nm beam expander

Beam expanders in laser system development are used to calibrate various components. The diameter of the laser beam at the output of the laser system matches the required diameter at the input of the objective lens. Beam expanders are also mainly used in laser material processing.

Fixed beam expanders are also designed for specific beam expansion applications, such as laser engraving.They also have anti-reflective coatings and high transmittance to maximize beam of light expansion efficiency and reduce losses.
