Default Thermopile sensor question

Hello guys,
I am working on a new design of the power meter that would work with all types of sensors, but I couldn't find the feedback voltage of the thermopile sensor such as Ophir or Coherent sensors. I find some information on Newport that says it is about 10mv/W, and some other off brand manufacture says 70-150 mv/W. Does anyone have experience with that? I am looking for the raw output of the sensor not the pre-amplified ones like 20c-a.


Thanks
Wade

Different sensors will have different outputs, usually the raw thermopile output is quite low though. Usually only a millivolt or two per watt but again greatly depends on the model and power range.

Which sensor model specifically? Both Ophir and Coherent have many, many different sensors.

I don't need to know the specific, I just need to know the approximate value so I can set up my op-amp.
