The Ion Beam Sputtering (IBS) coating, with its near-bulk ultra-high density, effectively suppresses optical absorption and significantly increases reflectivity. As a result, the mirrors deliver outstanding performance and an exceptionally high laser-induced damage threshold (LIDT), even under demanding laser environments.We offer plano-concave mirrors with a variety of radii of curvature (ROC), enabling flexible selection of optimal optical parameters tailored to different laser system designs. This helps to maximize laser transmission efficiency and enhance overall system stability.Featuring a smooth and uniform surface, the plano-concave mirrors can withstand high-power laser irradiation. Their low thermal expansion coefficient, high mechanical strength, and excellent stability ensure long-term reliable operation under high repetition rates and high energy density conditions.Whether used in precision scientific instruments, industrial processing equipment, or nonlinear optics and ultrafast experimental platforms, our mirrors provide solid optical assurance for your laser systems.。
Disclaimer:ROC and focal length values not explicitly stated in the product specifications are calculated reference values based on the coating design wavelength, and are provided for selection guidance only.
Notes:For best performance, store and use the mirrors in an environment of 25 °C and relative humidity of 40%–60%. If contamination occurs on the mirror surface, gently wipe with >99% alcohol and lint-free optical tissue. Do not use rough fabrics, water, or abrasive cleaners, as these may damage the coating.
