Sciencetech Large Area Thermopile Detector Head
|
Note: Our thermopile detector is inherently flat in response from 100nm to >100um but is window limited.
Note2: This thermopile head is useful for solar radiation measurements at power densities of 70-150mW/cm^2.
Note3: Thermopile detectors may be sensitive to temperature fluctuations and/or radiation from cell phones.

| Additional notes and clarifications:
|
| Sensitivity* |
Measured (and calibrated) in a 0.1 Hz bandwidth at 22 degrees Celcius using a 632.8nm
source chopped at 0.25 Hz with 50/50% duty cycle.
On board jumper converts sensitivity from total power to power density.
Sensor area is 28.3mm^2. Damage threshold => 500mW/cm^2 , 140mW total power.
|
| NEP* |
Typical, units are Watts/Hertz^.5, measured as per sensitivity.
|
| SatP* |
Saturation power. i.e. Output just below clip level. See damage threshold above !
