Relative Measurements from 0.1 to 30 THz
Broadband, room temperature operation, easier to use and less expensive than a Golay cell
Easy to Integrate Format
TO5 and TO8 packages make the QS-THZ detectors small and easy to integrate in an existing system
Several Sensor Sizes Available
Choice of 2 x 2 mm and 5 and 9 mm Ø
Calibrated at 0.63 µm
QS-THZ 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.
Test Box Available
Can be used with our QS-I-TEST test box which provides mounting and power supply
Permanent IR Window Options
Every model can be fitted with a permanent IR window to narrow the wavelength range:
- S5/8: sapphire (0.3 – 4.5 and 100 - 1000 µm)
- Q5/8: quartz (0.25 – 3.0 and 50 - 1000 µm)
- Si5/8: silicon (1.2 – 8.0 and 50 - 1000 µm)
