Laser Research Optics, Providence, R.I., has released a new line of CO2 laser mirrors, SuperHard Coat copper mirrors, that help reduce power loss and enhance laser cutting capabilities.
These mirrors feature a proprietary hard coating that provides 99.85% avg. reflectivity with a zero phase shift of < 2 degree @ 45 degree AOI for use in industrial CO2 lasers up to 10 kW. More durable and scratch-resistant than typical ZnSe based coatings per MIL-C-48497A, these mirrors help reduce power loss for consistently good laser cutting.
Available in plano, convex, or concave configurations in 1-1/2 to 3 inch O.D. sizes, these SuperHard Coat copper mirrors have a 40-20 scratch-dig surface finish and parallelism is <3 arc-min. They are available for Amada®, Bystronic®, Cincinnati®, Mazak®, Mitsubishi®, Trumpf®, LVD®, and similar lasers.
