Datasheet(CN) Datasheet(EN) PC-Gentec-EO User's Manual THZ-D User's Manual
Gentec-EO THZ12D-3S-VP-D0 THz detector for power measurements up to 3 W.
Key Features
Relative Measurements from 0.1 to 30 THz
Broadband, room temperature operation, easier to use and less expensive than a Golay cell
Flat Spectral Response
Get the best precision accross the entire wavelength range.
Measure Higher Powers
Up to 3 W of continuous power with the THZ12D model, the highest in our THz range of products
Large Aperture
Models range from 9 to 12 mm ? aperture.
Calibrated at 10.6 μm
THZ-D detectors are calibrated at a single wavelength (10.6 μm) and include wavelength correction data from 10.6 to 440 μm. They are used for relative measurements outside that range.
