Fabrication of Optical Glass
In a white paper, entitled “Fabrication of optical glass,” Manx Precision Optics (MPO) presents a general overview of optical glass manufacture.
The paper summarizes the steps of this process:
- Rough Shaping – Shaping of raw glass into a blank approximately 1 mm larger than the finished component
- Milling – Further shaping of optical surfaces to better than 0.1 mm and preparation for polishing
- Loose Abrasive Lapping/Grinding – Grinding or “Lapping” of the optic to remove damage from the previous step and shape the optic to within a few micrometres of the desired curvature
- Polishing – Polishing of the ground surface to the desired finish quality
- Edging – Realignment of the optical axis joining the two optical surfaces and the mechanical axis of the optic.
Manx Precision Optics (MPO) is equipped with facilities for the shaping, grinding, polishing and edging/bevelling of optical glass. Their glass fabrication department comprises industry veterans with the capabilities to achieve surface finishes with RMS roughness as low as ±0.2 nm (2 Angstrom).
