Last time Electrofreak was kind enough to answer my questions. Since then I have learned a little more and have alter my project slightly.
My New Question:
Still looking at using multiple LDs but I don't want to culminate them now. I want a wide bright beam. Would I be best to use 2 lens to get a solid beam or use a diffuser on each diode and then combine the diffused beams into a solid one?
If I want to use the 2 lens option, has anyone tried a concave mirror? If the mirror is uniform, and the diodes set in a ring, then they should all reflect into a single point in front of the mirror. I should then be able to get by just using a single diffusing lens to produce the beam? (If I have time I will draw a diagram to illustrate and post it tomorrow)
Thanks again for the info.
