Robert E. Parks·Aug 20Aligning a reflecting collimator to a fiber optic feedA question came up today that illustrates the primary function of the Point Source Microscope, or PSM, the transfer of an optical datum to…
Robert E. Parks·Aug 17Centering station used for lens inspection for “drop-in” lens assemblyWhen lenses are assembled using the drop-in method, the lens elements are constrained by the cell bore into which they are “dropped”. Fig…
Robert E. Parks·Aug 3Chapter 28 Another use for the Bessel beamWe recently began assembling a 10.6 μm interferometer using a CO2 laser as the coherent light source. Because most CO2 lasers are designed…
Robert E. Parks·Jul 30Chapter 27 Centering using Edge Thickness DifferenceIn the coming chapters, I will compare several methods of centering lenses where one degree of freedom is constrained. To keep things…
Robert E. Parks·Jun 29Chapter 26: My thoughts on opto-mechanical alignmentThis chapter takes a different approach than the previous ones. Rather than diving into a specific technical procedure, I want to share my…
Robert E. Parks·May 13Chapter 2 Radius measurement — the original use of an autostigmatic microscopeAfter finishing Chapter 1, I was going to jump right into discussing using the PSM for optical alignment. As I started an outline for this…
