Hamamatsu produces THz electromagnetic waves emission/detection modules, in which a LT-GaAs (Low-Temperature-grown GaAs) based photoconductive antenna chip and a lens for THz electromagnetic wave are integrated. This module also has a SMA connector, which facilitates easy connection to other equipments. Alignment between the photoconductive antenna chip and the lens is factory set. A M6 tapping hole and two M2 tapping holes are prepared on faces to help easy setup.
 

There are three prepared patterns of photoconductive antenna chips; Dipole, Bow-tie, and Spiral. When other pattern of photoconductive antenna chip is necessary, please contact HAMAMATSU sales person.   Applications for these devices include

• Nondestructive  Inspection  for  Industrial  Field
• Non-contact  Measurement  for  Biological  Tissue
• Far-infrared  Spectroscopy
• Material  Analysis
• Structure  Inspection
• Security
