| Maximize laser beam hitting cadmium photocell |
| (1/1) |
| fixit7:
I am trying to maximize the amount of light that a red laser produces when it hits a cadmium photo cell. I went from a photocell with a small area to one with about double the area. I salvaged this from a laser printer and was wondering if that clear thing is a fresnel lens? Am also trying to figure what that clear led is.? There is a drawing on the circuit board that looks like this. LD1 A |-->|C Thanks. |
