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.
