Okay, now I have another question. I want to use a laser diode for illumination. Basically more focused and powerful than a flashlight, but less focused than a pointer.
Okay, so just run the focus out on your lens, right? Well, there is one more thing. The module containing the diode can be rotated one or so degrees to aim it. This is inside a sealed box (waterproof) and I need the to be able to adjust the beam size (focus) from the outside.
Like how the aixiz housings can be focused with the knob, only the diode will not necessarily be inline with the lens.
Is it possible to alter the focus of a beam coming in at an odd angle without altering its direction? It doesn't seem physically possible, but then again, I don't know much about optics.:thinking:
I was thinking maybe focusing the light into a beam, aiming that(it will only be "aiming" about a degree) beam through another lens that is attached to the outer case and can be focused. But again, it seems like that would alter the beam's aim...
Does any of this even make sense? I'm having a hard time explaining...
Thanks in advance for any help!
