Sciencetech TeraHertz Lithium Tantalate Pyroelectric Detector Heads
|
Note: Our pyroelectric detectors have inherently flat response from 100nm-1000μm but are window limited.
Note2: Pyroelectric detectors REQUIRE chopped radiation input and a synchronous output detection system.
Note3: Pyroelectric detectors may be sensitive to rapid temperature change, vibration and/or cell phones.

| Additional notes and clarifications: |
| Sensitivity* |
Measured (and calibrated) in a 1 Hz bandwidth at 22 degrees Celsius using a 632.8nm
source chopped at 8.5 Hz with 50/50% duty cycle.
Warning: Response (and calibration value) will be reduced by 3% with 50/50 chopped
input at 2 octaves (4x/25%) above/below the -3dB points. i.e. -3% at 2Hz and 40Hz typ.
On board jumper converts sensitivity from total power to power density. (uncalibrated)
|
| NEP* |
Typical, units are Watts/Hertz^.5, measured as per sensitivity.
|
| SatP* |
Saturation power. i.e. Output just below clip level.
|
| Quartz |
May be quartz or fused silica.
