I am trying to build a SPR setup at home which is based off this diagram:
I wanted to try to miniaturize it and had some concerns about my strategy.
So I was thinking I could buy a big prism and maybe use a glass cutter tool from amazon to slice it cross-section wise to make it smaller. Although I am uncertain of this strategy or if there is a better method. As for the laser, I can find small lasers on amazon, but I was wondering which manufacturers could build me a laser smaller than the size of something like a finger nail or even smaller?
