High Temperature resistant IR mirror

[saverin]

I am attempting to take a thermographic image of a flat plate burner from above, and this requires that I use a 45 degree mirror to redirect the radiation. At the maximum output of the burner, I have recorded a temperature of approximately 95 C where the mirror needs to be placed.

I am having trouble sourcing a mirror that will provide sufficient IR radiation reflection and be able to withstand the higher temperatures.

Does anyone have any idea where I could find such a mirror?

Thanks.

"sufficient IR radiation reflection" ???

The source must be quite hot; there should be plenty of photons, even if the reflectivity is degraded. What reflectively requirement are you specifying?

Try a gold mirror and if necessary air cool it.

For thermal imaging, you probably need a "first surface" mirror.
Googling high-temperatre first-surface mirror lead to this:

They give the reflectivity for 400-800nm. If your camera operates at longer wavelength, you'd have to ask them for characteristics in that range (or search another)
