Hi! I'm working in a powerfull 650nm laser made from DVD-RW LD and optics. I have many beam splitters, some aspherical lens and spherical lens (the objective lens) and concave lens.
In my search for a lens that uses all the output light from the laser diode (to improve performance) I found the objective lens perfect for this, it have a small focus distance, but as all spherical lenses, it have the spherical aberration "bug", in my last test I got this:
I wanna get something like this:
How I can correct this? Thanks! :beer:
