Diamond Turning


The Edmund Optics® diamond turning facility is staffed with experts with 10+ years of experience in diamond turning a variety of materials utilizing various techniques including, but not limited to, standard turning, fly cutting, and post polishing nickel.

Single point diamond turning is a manufacturing technique for producing precision optical components including off-axis parabolic (OAP) mirrors, off-axis elliptical (OAE) mirrors, spherical and aspheric lenses, and flatwork. Edmund Optics® offers build-to-print or custom capabilities to meet your specific application needs and diamond turns components out of metals, crystalline materials, and plastics. 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.
