Hi there
I figured this may be the best place to start, hoping to tap into some knowledgeable people here as I'm a newbie to the physics behind lasers. How do you determine a materials opacity relative to a particular wavelength of light?
The reason I ask is I'm attempting to build a 3D printer and need a laser which is will pass through glass but not aluminium. Can anyone help?
