Single Point Diamond Turning (SPDT)

Single-Point Diamond Turning (SPDT) new generation lathes produce high-end optical surface finishes and consistent performance in plastic and metals which producing precision optical components including off-axis parabolic (OAP) mirrors, off-axis elliptical (OAE) mirrors, spherical and aspheric lenses, and flatwork. The SPDT process is also used to machine the optical surface on the inserts used in the molding process.

TAYFX offers build-to-print or custom capabilities to meet your specific application needs whether standard or custom, our expert optical design and diamond turning staff can develop customized solutions incorporating custom sizes and shapes, a variety of metal mirror coatings, or other modifications.

The SPDT process can fabricate small quantities of custom optical prototypes prior to production molding the optics.
