Ok, so I suck at physics. I know it is my weakest area, and so, plan to devote most of my time to it this summer when I am studying for my MCAT. I will be doing focused review and practice with Examkrackers and Berkely.
I know people might jump at this...

If you'r developing something to do physics calculations then you should know the physics and the math, likewise for mathmatics software.

CO2 laser rifle optics... beam diammeter HELP!!!! Hello everyone, I am pretty new to the forum (not to lasers). I have a question about optics for my co2 laser rifle I've recently built. I'm trying to pinch the beam down into a thin parallel beam with...

There's no cheating around the laws of physics and optics.
Beam diammeter HELP!!!! Yeah you're missing out a couple of things beam as only reducing it in the first place .

Being a graduate of physics is never a disadvantage in any way.
Now, there is no special challenge that physics graduates face in the labor market and other graduates do not face.

Some where I read, blackening is the least important thing when designing optical system. I did not see any blackening on TMB monos and my AP 130 GT. I like them better aesthetically with non-blackened edges.

Like all optics made by AP the current Barcon was introduced.
It is definitely equal to the quality of the Zeiss orthos and barlow IMO .
I think it's one of the finest optics I own.
Is that the AP Barcon is simply outstanding.
