THZ12D-3S-VP-D0

P/N 202229

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 Ø 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.
