Dear Sirs,

For measuring black body radiation of a heat source in a temperature
range of 500K to 1300K we need a radiation detector with almost frequency
independent sensitivity. At the moment we use a thermopile with a
sensitive area 1.5*1.5 mm**2 and a responsitivity of 20V/W.


Can you please let us have information about adequate thermopile detectors
and prices.

Sincerely,

Karl Siebinger
