Applications of Optics

I have experience with optical components, assemblies and instruments for various applications.  Each has its own particular requirements and I've learned something from each that I can bring to the others.

Scientific

Ion and dye lasers, fusion lasers, etalons, Lyot filters, Fresnel and Mooney rhombs, multiple wavelength and achromatic waveplates, prisms, photo-elastic modulators, non-imaging concentrators, imaging optics, cryogenic assemblies, infrared and ultraviolet optics.

Medical

Immersed lenses, dichroic filters, infrared and ultraviolet optics.

Telecom

DWDM etalons, micro-waveplates, multiple port prism assemblies, instruments for measuring retardance and free spectral range.

Metrology

Components for distance-measuring interferometers, instruments to measure retardation, extinction and free spectral range, etalons, frequency standards. A whole bag of little-known tricks and techniques for optical shop measurement.

Astronomy

Massive aspheric mirrors, high finesse etalons, null testing, Hartmann testing, Shack and Smartt and Saunders interferometers, whiffletree mounting.

Industrial

Scanners, FLIR, high power CW and Q-switched optics, water-cooled and gas-cooled, heat-sinks and beam dumps, in Cu, Mo, Si, Ge, ZnSe, GaAs, CaF2, SiO2,  Al2O3, gain media in rod and slab form, and aspherics including off-axis.
