Method for producing a mirror from a titanium-based material, and a mirror made from such a material

摘要

A method for producing a mirror ( 10 ) from a titanium-based material by using the technique of ultraprecision machining. The mirror produced using this method has both a shape accuracy and a surface roughness in the submicrometer region. The mirror ( 10 ) is made from a titanium-based material having a shape accuracy and a surface roughness in the submicrometer region, whose basic shape ( 11 ) has a has a reflecting surface ( 12 ) having a surface roughness of less than 60 nm, and in particular of less than 30 nm.
