Beam homogenizer

Device to create a more uniform laser beam

A beam homogenizer is a device that smoothes out the irregularities in a laser beam profile to create a more uniform one. Most beam homogenizers use a multifaceted mirror with square facets. The mirror reflects light at different angles to create a beam with uniform power across the whole beam profile. Some applications of beam homogenizers include their use with excimer lasers for making computer chips and with CO2 lasers for heat treating.
