Single Point Diamond Turning
©️ Private
Single point diamond turning (SPDT) is the process of turning optical elements with a diamond-tipped cutting tool and is used for high-quality aspheric optical elements. We use Single Point Diamond Turning to produce ultra-precise infrared optical components such as infrared aspheric, diffractive, and spherical optics and gratings.
The process of mechanical machining infrared optical components using lathes equipped with diamond-tipped tools enables us to manufacture crystal-based optical products with a greater degree of precision than otherwise possible with standard machining techniques.
Get in touch with us to discuss how we can support your business.
