Relative Measurements from 0.1 to 30 THz
Broadband, room temperature operation, easier to use and less expensive than a Golay cell
Wide Dynamic Range from nW to mW
With state of the art pyroelectric sensors, measure down to 50 nW with 1 nW resolution.
Several Sensor Sizes Available
Choice of 5 mm and 9 mm diameter
Calibrated at 0.63 µm
THZ-B detectors are calibrated at a single wavelength (0.63 µm) and include typical wavelength correction data from 0.25 to 440 µm. They are used for relative measurements outside that range.
SDC-500 Optical Chopper
All THZ-B detectors require the use of an optical chopper, like our SDC-500, to sync the signal at either 5 Hz (DA models) or 25 Hz (DZ models).

THZ-B-DA DETECTOR AND OSCILLOSCOPE
Here is a basic analog set up that would be useful if the optical power of the source was about 5 µW or greater. The output of the THZ5B-BL-DA detector would be approximately 600 mV @ 5 Hz chopping frequency, giving plenty of signal for an oscilloscope. Simply read the voltage output and divide by the Rv factor (V/W) of the detector to measure the intensity of the source in Watts. Also consider applying a wavelength correction factor under certain circumstances.
THZ-B-DA DETECTOR AND LOCK-IN AMPLIFIER
This is another analog set-up option that we recommend if you have to measure very low power levels (i.e. less than 5 ?W) where the signal may be buried in the broadband noise. The voltage output of the analog THZ-B-DA detector, powered by our T-RAD-ANALOG, is routed to the Lock-In Amplifier input, and the Sync Output of our SDC-500 Chopper is connected to the reference input. The Lock-In Amplifier will lock on the chopping frequency and you can dial in a long integrating time and measure a very low RMS voltage. The voltage divided by our Voltage Responsivity (V/W) equals the power of the source.
