Optical fabrication lab

Included in the CAO lab floor space is a fully functional fabrication machine shop and a rough cutting/fabrication assembly area.

Our primary Fabrication facility.

Should additional fabrication machines, tooling, or fabrication personnel be required for large grants, projects or quick turnaround work, the CAO also has shop privileges with the UA- Huntsville Rotorcraft Systems machine shop and their 30+ year experienced machinist. Having these resources readily available, the CAO is poised to quickly fabricate prototypes to get designs off the paper and onto the table. The CAO is also available to offer fabrication and polishing services for prototyping to local R&D companies in the Huntsville community.

Filling out a simple service agreement form, the CAO can bring a design or proof of concept to life at a very competitive cost with a short delivery schedule. Mr. Ted Rogers is our Fabrication Coordinator at the CAO. Mr. Chris Underwood is our master machinist, fabricating our optics and mechanical structures for many years and operates the diamond turning machine and, when it arrives, our new ZEEKO deterministic polishing machine. Our Optical Fabrication lab houses a newly installed NANOTECH UPL250 single point diamond turning (SPDT) machine, two optical microscopes, a spacious clean room for inspection, and classical polishing equipment. We fabricate prototypes for complex optical systems, we refurbish existing optical systems, we make our own tooling and we help to mature educational and industrial research concepts from the idea stage to a working system. We will be adding deterministic polishing machine(DPM) to our fabrication suite in Janurary of 2011 with the addition of a ZEEKO IRP600 DPM.
We are currently rebuilding a MOORE M48 DTM donated from NASA and perfectly stored. It will make a 48 inch diameter sphere and is due to be introduced to our hardware list next year in 2011.
