Silly question but how does a 4m aperture focused onto a smaller area not concentrate the heat and melt the instruments?

It's highly filtered, you are only getting a small slice of all of the wavelengths. Only a tiny fraction of all that energy hits the photo collector. I believe the collector is also actively cooled, but I might be wrong there.
