OSA | Comparative analysis of oxidation methods of …

Coination of the oxidation of reaction-sintered silicon carbide (RS-SiC) and the polishing of the oxide is an effective way of machining RS-SiC. In this study, anodic oxidation, thermal oxidation, and plasma oxidation were respectively conducted to obtain oxides on RS-SiC surfaces. By performing scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM-EDX) analysis and scanning

Foam-core mirrors architecture by Ultramet

Mirrors have been fabried with both flat and curved optical surfaces, and several material systems have been used. Silicon and silicon carbide systems offer the greatest stiffness-to-weight ratio. Advantages Optical properties meet or exceed those of current

LBP Optics - appliions - scanning

It is also possible to make aluminium mirrors lighter by using ribbed designs on the rear surfaces, like those seen on most silicon carbide scanner mirrors. Our mirrors have an improved resistance to laser damage due to the layer of electroless nickel that we deposit between the metal and the coating.
