OK I, deleted my last 2 posts in order to post something more constructive. 1st, thanks for the good info, Survey. Any idea what power and size cylindrical lenses are needed? 2nd. I'm not looking for a perfectly circularized beam; a 3mm square at the aperature and a small square at, say, 50 ft. (30x30mm) would suit me fine. Ive been able ,through different lens combinations, to obtain a small dot size at the ap and good divergence but there is some loss, and the beam isnt as clean as I'd like it to be. I've heard that this divergence (5~7 x 50 deg) is a tall order to tame. Using 1 small aspheric lens from a cd reader I can produce a clean 'line' (still with some loss) from the ap to 100 feet. Can a rod or cyl lens be used after a primary aspheric lens that's very close to the diode window? (~1-2 mm)
to tame the fast-axis? And lastly, Do you have one of those diodes and are presently working on it, or is the project completed successfully?
Pictures would be nice. "We love pictures."

Have a good one,
