Low cost thermopiles

Hi,

Thermopiles are used for non contact temperature sensing, and are very popular in the world of low cost UAV.

I’m interested in this type of thermopile:

Though as you can see the price tag per unit is simply outrageous.

This thermopile comes with onboard ADC and DSP, and outputs data via SMBus or PWM.

Any idea where I get this chip for cheaper, or if a cheaper equivalent exists?

Thanks!
