Temperature control is crucial, because the surface must be accurate on distance scales shorter than the wavelength of light. Views Read Edit View history. Electron Beam and Laser Beam Machining. Your account has been activated.

Please help improve this article by adding citations to reliable sources. Diamond turning is most often used for making infrared optics, because at longer wavelengths optical performance is less sensitive to surface finish quality, and because many of the materials used are difficult to polish with traditional methods.

Methods of mounting of jobs npfel cutting tools in machine tools. Materials that are readily machinable include: The machined element is attached to an air chuck using negative air pressure and is usually centered manually using a micrometer. Don’t have an account?
