computer projector design 1

[edwsshaw1]

Any thoughts on lens system for redesigned computer projector would be appreciated, specifically, lower cost systems still capable of resolution for 3' X 5' application.
I also have a post in hardware architecture engineering, Dec. 19, 2000.
Thanks,
Ed Shaw

Check Edmund Scientific for surplus lenses: For that application you need a very fast lens if you wish to project it onto a projection screen of the size that you want. The computer CRT needs to be a special high intensity version to get sufficient light to the screen, as well.
