P/N 202288

Terahertz detector with integrated analog module for power measurement up to 140 μW.


Relative Measurements from 0.1 to 30 THz

Broadband, room temperature operation, easier to use and less expensive than a Golay cell

Measure Power from nW to mW

With state of the art pyroelectric sensors, measure down to 100 nW.

Integrated Analog Module

Plug the head directly to your oscilloscope or lock-in amplifier.

Battery or AC Powered

Includes 9V battery and AC power eliminator

Calibrated at 0.63 µm

THZ-I-BNC 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.
