Aspherical Optics are our Specialty!

ROC has developed robust processes and testing methods to produce high quality aspherics of all types from 0.25 meters to 2.0 meters in diameter.

Our CNC machine can lightweight your blank as is usually done with secondary mirrors for telescopes. Our computer controlled polisher and integrated vertical test tower equipment equipped with a phase-measuring interferometer allows ROC to manufacture aspherics to high accuracy.

ROC has manufactured many large telescope systems up to 2-meters in aperture. Our computer controlled methodology with carefully designed polishing tooling allows us to produce these LARGE aspherical mirrors to high figure quality with smooth surfaces having very small mid-frequency error and microroughness less than 10 Angstroms rms.

Types of Aspherical optics ROC manufactures:








Let ROC make those easy to design but difficult to make aspheric optics.

We have the knowledge, the know-how and the experience!
