Features

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).
