Introduction

The sensing element used in the PASCO CI-6628

Infrared Sensor is a thermopile. Thermopile

detectors are voltage-generating devices that can

be thought of as a miniature array of

thermocouples. The thermopile is a high output,

thin film, silicon based device which has 48

thermopile junctions. The active or ‘Hot’ junctions

are blackened to efficiently absorb radiation. The

reference or ‘Cold’ junctions are maintained at the

ambient temperature of the detector

The blackening material used on the ‘Hot’

junctions is capable of absorbing radiant energy

from ultra violet to the far infrared. In order to

limit the spectral sensitivity, optical filters and

windows may be placed in front of the detector.

The window installed in the detector is a ruby-

based material which has a spectral response from

visible light to the far infrared (about 40,000 nano-

meters). The hermetically sealed detector is heat

treated and filled with argon gas to improve long

term stability.

The absorption of radiation by the blackened area

causes a rise in temperature in the ‘hot’ junctions as

compared to the ‘cold’ junctions of the thermopile.

This difference in temperature across the

thermocouple junction causes the detector to

generate a positive voltage. If the active or ‘hot’

junction were to cool to a temperature less than the

reference or ‘cold’ junction the voltage output

would be negative.

The output of the thermopile detector is presented

to a gain selectable amplifier. The GAIN switch

located on the top of the sensor is used to adjust the
