Reynard Corporation (San Clemente, CA) has released high precision coatings Galvanometer mirrors for laser system applications such as scanners, bar code readers, sweeping remote sensors, marking systems, and laser light shows. A mirror is modulated on its centered axis, causing a static laser beam to scan in a one-dimensional orientation. Adding a second Galvo mirror allows for scanning in two dimensions. The Galvo mirror coatings can achieve reflectivity of greater than 99.9% and are able to withstand the most rigid durability requirements per military specifications, including temperature/humidity and salt fog requirements per MIL-C-48497A.
