I need an expert in optics and lenses to determine what lenses I need to project a light beam. I want to design a simple light beam projector that projects a 1 inch size dot of light 25 feet away. I know this is possible because I have a working system that does this but I need to make another just like it. The tube and light are easy but I do not know how to reproduce the lenses. I need someone who can design the lenses(ie tell me what numbers I need to have them manufactured). I need someone who can also recommend a company that can produce custom lenses in small quantities at a reasonable price and tell me what information I should provide to them to make these lenses(focal point, convex/concave? whatever is needed) or if you know a company that provides pre-made lenses that would be even better. Attached is the layout with measurements. This was originally used in an old arcade game where a rifle fired a light beam. The light would illuminate very bright, the light rays went through the lenses which were at both ends of the barrel as shown in the diagram, and approx 25 feet away it would project a circle of light about the size of a quarter(1 inch). The dimensions are on the diagram. Please let me know if you have experience with optics. Thanks Update: A number of people have asked about the light source. Just treat it as a point source or a generic directional source, it will be a bright white LED but I do not think it will matter for the calculations. ## 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. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform This is an engineering project. Final deliverables are the focal distance and lens type plus any additional numbers needed to have these lenses custom made or to purchase existing premade lenses.
