I just bought this sensor
http://www.pololu.com/catalog/product/1061
I programed it and it works great.
The only thing I notice is that it has a wide viewing angle and averages all the temperatures so if there is something really hot but small like a candle flame it doesn't really provide the true temperature unless it is about an inch away. is there anyway to decrease it's field of view? could a lens be used?

thank you for you help.

Or a slit?

I tried that and it averages the area that is covered with the area of the slit so a 200 degree light bulb registered at 80 degrees at 2 inches.

If you can find something that reflects infrared then you could put a parabolic reflector behind the sensor (and turn the sensor back to front). I'm not sure where you'd find a suitable reflector though - perhaps you could find a reflective lamp bulb that reflects IR well? I'm not sure how easy those would be to find, but if all else fails I know that IR reflector lamps do exist.
