Diamond turning techniques
币游网址 AMOS polishes the substrate then engraves the gratings using diamond turning techniques. This also enables a wide range of gratings.
币游网址 Diamond turning technique allows to manufacture small optical pieces for infrared applications and also, with post-polishing, for visible or ultraviolet. We produce concave and convex mirrors up to 500 mm diameter with extreme asphericities, also off-axis devices and freeform surfaces.
