Terahertz detector THZ5B-BL-DZ-D0

opticalwith pyroelectric sensor

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 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 T-RAD The T-RAD is a microprocessor-based digital radiometer that includes a 12-bit ADC and unique DSP lock-in software. It is powered by a USB connection, which also acts as a virtual COM port. When a THZ-B terahertz pyroelectric detector is plugged into the T-RAD module, the module reads the content of the head's EEPROM, which identifies the detector and provides calibration and wavelength correction data. The LabView software supplied with the device makes it very easy to set up the radiometer, measure a THz or broadband source and record data. The software is compatible with Windows 7, 8 & 10.
