Maximize laser beam hitting cadmium photocell
« on: June 07, 2019, 02:17:21 am »
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.
