PROVIDENCE, R.I., Aug. 14, 2013 — Laser Research Optics, a division of Meller Optics Inc., has released a line of gold-plated copper mirrors designed for high-power Mitsubishi lasers. The mirrors are suitable for beam bending in all paths and guidance systems, from simple measurement setup to high-performance cutting. Manufactured with >99 percent pure gold deposited onto oxygen-free high-thermal-conductivity copper, they are offered in three plano types: zero and 90° phase shift, and 98.8 percent resonator mirrors. With OEM quality, they provide 1/20 power flatness, 1/40 irregularity at 10.6 µm, and surface quality of <5 nm rms with 40-20 scratch-dig. The mirrors are available in 50- and 60-mm, and in 3-in.-diameter sizes with +0/–0.12-mm tolerance.
