Default More project questions.

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.

Default Re: More project questions.

As stated here is the image I was talking about...

Please let me know if this will create a closed circuit that will trap the light.
