Blue laser converted to white light 3X 5X beam expander

Blue laser converted to white light 3X 5X beam expander

Beam Expanders,3x, 5x,  Options of Expansion Power. 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 afocal 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.
