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: 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).
  
USER-FRIENDLY SOFTWARE WITH MANY FEATURES (WHEN USED WITH T-RAD-USB):
  • Strip chart, statistics and tuning needle displays
  • Controls and power display always visible
  • Tuning needle display includes min/max indicators
  • Data logging for long term testing

Applications

  • Security scanning of people and baggage
  • Nondestructive testing of airplane wing structures
  • Early detection of cancerous growths
  • Noninvasive testing in microelectronics
  • Terahertz spectroscopy
