Is there a good reflector for IR? Can a standard front surface mirror be used or are there other materials available?
The best choice for a thermal energy reflector is a front surface gold coated mirror. The next best choice is aluminum – a common material for front surface mirrors. Other polished metals would also work, but they tend to be slightly less reflective, or are prone to oxidation.
