Diamond-turning technique from Edmund Optics available
Single-point diamond turning produces off-axis parabolic (OAP) mirrors, off-axis elliptical (OAE) mirrors, and precision metal, plastic, and crystalline optical components. The manufacturing technique involves mechanical machining of precision elements using lathes or other machines equipped with diamond-tipped bits. RMS surface roughness values are down to 30 Å and coatings are available.
