Literally
Was just playing around with a dual cascade TEC system and decided to put a 445nm laser ontop, just for fun. It's temperature was sitting at around -10C, although not surprising considering it's a heatsink Would go much lower if I had some bigger TEC's, considering trying it with a 500W TEC when I order one.
Even though it's only a 8nm ish wavelength drop, it's actually visually a deeper blue!
