Eliptical Math/UV Radiation Problem(repost)

I'm building a UV curing system which uses a reflector to focus beams of UV light on a certain area. The reflectors are eliptical (focused beam). I'm looking for the appropriate measurement for the dimensions of the elipse based on the needed size of the beam. This measurement would be based on the following criteria: width of the focused beam distance of the lamp from reflector (focus) diameter of the lamp lamp distance from curing surface any other information you need. The reflectors are made of polished aluminum and the lamp is a 5" arc at 200WPI. I need 200WPI of focused light that will shine through the bottom of the reflectors. Please look at the attached picture as an example. If you can get a measurement from the picture based on their numbers, I will accept that to. If you need any other info, please let me know. Thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
