Super-Smooth Optical Fabrication Controlling High Spatial Frequency Surface Irregularity (ABSTRACT)

ABSTRACT: A paper by Del Hoyo, et. al., showing how the MicroFinish Topographer (MFT) was used for in process control assessment of the removal of high spatial frequency polishing errors during polishing as a function of type of polishing compound and polishing pad. The MFT was particularly useful for determining when a surface was fully polished out, that is, had no defects left from previous steps in the lapping and polishing process.

The PSM is an ideal tool for finding the center of curvature of a ball or the axis of a cylinder. The question is for how small a ball or cylinder can the PSM do this?

The smallest article that was readily available was a piece of monofilament 8 pound test fishing line that was 290 μm in diameter. There was no problem finding the axis of the fishline, and separating the Cat’s eye reflection from the surface from the confocal reflection of the axis. The experiment was done with a 5x objective, and the result would have been even more definitive using a 10x objective.
