The most recent project was a laser based scanning inspection system using a rotating polygon and laser diode.  Gibson Optics designed the entire system including the optics and mechanics.  The system included two zoom systems for spot size length\width\focus, and an F/Theta lens.  All the optics including the F/Theta lens were designed, assembled, tested and deployed (performance was as designed).  The final customer is very happy with the performance.

Worked on an all mirror projection aligner (1.5 micron resolution at 365 nm). Responsible for alignment, testing and troubleshooting of ring field projection optics which consisted of two spherical mirrors and three flat mirrors in a folded configuration. Responsible for the optical and mechanical design and assembled an interferometer using a 442 nm HeCd laser which was used to align and test the two spherical mirrors independent of the flat mirrors. Responsible for layout and testing of arc lamp illumination system.  Redesigned a 1X relay internal to illuminator.  Developed testing tooling for verifying alignment. Extensive testing using Zygo interferometers which I procured.

Responsible for specifying and purchasing multiple interferometers for several companies.  Developed testing methods and trained QC personal in their use.  Interferometers were used for trouble shooting performance issues by analyzing various optical components.

Laser medical devices. Performed optical design on a HeNe/CO2 optical system used for various kinds of surgeries (hand, ear, throat, brain). Developed attachments for different kinds of uses. Received a patent.

Responsible for optical and mechanical design of a mass memory device using laser diodes and an Argon laser. The argon laser device used two acousto-optic crystals for modulation and scanning. It incorporated an auto-focus, and produced 1 micron spots. The device was successful.

Assisted developing 1X projection alignment optics and illuminators for step and repeat projection aligners. The lenses were capable of 0.7 micron resolution over quite a large field. Extensive testing (Zygo interferometer, HP interferometer), trouble shooting, vendor relations, working with QA personal. Designed test equipment, procured 5 different interferometer systems. Was a key trouble shooter for discerning lens performance issues.  Was key person responsible for all melt re-computations (42 times over 7 years) for optimized performance. Coating specifications and procurement.  Redesigned illuminator and responsible for getting the mechanics designed.  Wrote lots of procedures for alignment, and QC. Received a patent for a deep UV 1X lens with 0.5 micron resolution.

Performed optical design on a projection lens for AMLCD flat panel inspection equipment. Optical design and mechanical layout of a LED based illumination system.  Supervised a mechanical designer who designed the mounting hardware to my specifications.

Optical design of 1.5 micron scanning projection aligner lens. Also illumination design using a Mercury arc lamp.  Received a patent for this project.

Worked on video projector including: Investigation of resolution, color coordinates and lumen output.

Designed multiple lenses in scanning inspection equipment for a major equipment supplier (3.5 micron at 365 nm).  Patent in progress.

Designed a built off-axis telescope including fabrication of mirrors.

Used and designed optics to work with microscopes and microscope illuminators

I have become a decent machinist learning to program an internal Gibson Optics CNC machine.  Also, extensive use of a lathe, drill press, band saw and other tools.

Excellent skills for troubleshooting opto-mechanical assemblies.
