Introduction

The sensing element of the Broad Spectrum Light

Sensor (CI-6630) uses a thermopile as a detecting

element. Thermopile detectors are voltage-

generating devices that act like 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 the ultra

violet to the far infrared range. To limit the spectral

sensitivity, optical filters and windows may be placed

in front of the detector. The window installed in the

Broad Spectrum Light Sensor’s detector is BaF

which has a spectral response from 300 to 10,000

nanometers. 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 temperature rise in the “hot” junctions, as

compared to the “cold” junctions of the thermopile.

This temperature difference across the thermocouple

junction causes the detector to generate a positive

voltage. If the active or “hot” junction cools to a

temperature less than the reference or “cold” junction,

the voltage output becomes negative.

The output of the thermopile detector is presented to a

gain selectable amplifier. The GAIN switch on the top

of the sensor is used to change the signal output (voltage)

of the sensor in experiments where the output signal is too

low, such as in dim light conditions, or when the signal

is too high, such as in bright light conditions.
