Diamond Turning
Diamond Turning
RPO's Precision Machining Group is comprised of workmen that have 10 to 25 years of experience in diamond grinding and polishing of all types of optical surfaces including spherical, aspherical, acylindrical and freeform optics to form errors of less than 1/10th λ accuracies. Our diamond turning facility is staffed with toolmakers with 15+ years of experience in diamond turning and optical tool surface generation.
