Recently, Brinksmeier et al. offered a 350 nm stroke FTS working at frequencies up to 10 kHz, which can be used for the technology of holograms . Another instance illustrating the progress that has been made in micro-structuring of optical surfaces by diamond machining is proven in determine 6. For a very lengthy time it was believed that hexagonal nook dice prisms, which supply a a hundred per cent yield of retro-reflected mild, would be inconceivable to generate by diamond machining owing to alternating convex and concave corners. Instead, it was thought that solely triangular prisms could possibly be machined, that are all convex, by intersecting three techniques of V-grooves fly-cut into a metal substrate.

On the other hand, in the case of Ni, flat sq...
