The nature and quality of a surface’s topography can play an important role in a part’s performance and expected longevity. The complexity of a surface topography means that while commonly used ISO 25178-2 height based statistical metrics are capa...
A unifying theme of this thesis is the implementation and characterization of point probes for surface metrology. The implementations include two optical non-contact profiling methods; fiber-based Fabry-Perot interferometry, and confocal microscop...
The advent of sub-aperture computer-numerically controlled (CNC) manufacturing techniques has enabled new opportunities for high-performance optical components and systems. Freeform and other challenging designs are now possible like never before....
The optical pitch polishing process has been used over 300 years to obtain high quality optical surface finish with little subsurface damage. A pitch tool consists of a metal platen coated with a layer of polishing pitch whereby pitch is a highly ...
