Material that reflects light, but not heat
Material that reflects light, but not heat
(OP)
I have a design problem that I'm trying to resolve and I was wondering if someone could help me:
I need to reflect light from a lamp source to a single direction by means of a reflector. The only problem is that I have to maintain the lamp temperature at a specific temperature. This creates a physical contridiction because the reflector also reflects the radiant heat, and raises the temperature of the lamp.
The solution to this problem will require a material that reflects light, but also absorves heat. Does anyone has any information on such material?

Many optical suppliers sell high-end or specialty cold mirrors. Edmund scientific has flat ones for relatively cheap. As ornerynorsk said, most precision, non-flat cold mirrors are manufactured for OEMs (medical equipment is a big application - I bet your teeth don't get hot under that lamp at the dentist!)
