Description
SPAWR Industries, Inc. is renowned for its exceptional quality in the production of metal mirrors, specifically designed for high-energy laser applications. Located in Lake Havasu City, AZ, SPAWR has established itself as a leading supplier of state-of-the-art metal mirrors, offering unparalleled surface damage thresholds for medium and long wave infrared lasers. The uncoated copper mirrors produced by SPAWR are crafted to meet the highest standards, ensuring optimal performance without the necessity for additional high reflectance coatings. However, for those requiring enhanced reflectivity, options such as vacuum deposited protected silver or electrochemically deposited hard gold coatings are available.
SPAWR's mirrors are meticulously engineered to cater to the demanding requirements of very high-power laser research. The optical characteristics of these mirrors are optimized for 80% of the mirror's diameter, with a standard wavelength of 10.6 micrometers. The mirrors are available in various standard radii, including concave options of 1M, 5M, 10M, and 20M, suitable for diameters up to 4 inches. For larger mirrors exceeding 16 inches in diameter, SPAWR offers custom solutions tailored to specific needs, with quotes available upon request.
Each mirror is accompanied by a protective shipping and storage container, ensuring safe transportation and longevity. Notably, the 12-inch and 16-inch diameter mirrors feature a lightweight ribbed structure, enhancing their practicality and ease of handling. SPAWR's commitment to quality is evident in the precise specifications of their mirrors, which boast a reflectivity of 99% at 10.6 micrometers, surface accuracy, and smoothness that meet stringent laboratory and industrial grade standards. Constructed from high purity copper, these mirrors are designed to withstand the rigors of high-power laser applications, making them an indispensable component for researchers and industry professionals alike.
