Diamond Turning


Single Point Diamond Turning is a manufacturing technique for producing off-axis parabolic (OAP) mirrors, off-axis elliptical (OAE) mirrors, and other precision metal optical components. Off-axis focusing mirrors are aberration-free across a broadband wavelength range, making them ideal for use in instrumentation and laser systems including Schlieren, MTF, FLIR, and FTIR, along with IR lasers such as Quantum cascade lasers. Edmund Optics® offers build-to-print or custom capabilities to meet your 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.
