Pre-assembled Terahertz Time-Domain Spectrometer
 
 

The pre-assembled THz systems are designed to use a fs laser provided by the customer. The beam paths for the emitter and detector antennas will be pre-aligned on an optical breadboard. Therefore, it is only required to feed the laser beam into the optical setup. Hence, the system is designed for customers who are familiar with optical setups but may not be as familiar with THz spectrometers. The linear stage and the data acquisition system are controlled using the T3DS software package that comes pre-installed on a laptop.

We provide spectrometers for pulse lasers with 780 nm, 1060 nm and 1560 nm wavelength with the following parameters:

  Pulse duration   100 fs
  Repetition rate   50 - 100 MHz
  Average optical power  ≥ 30 mW (free space antennas)
 ≥ 50 mW (fiber coupled antennas)

  • The pre-assembled THz spectrometers come on a breadboard without housing and with the T3DS software package installed on a laptop. For an additional price of EUR 4,700 the spectrometer can be delivered with housing.
  • In case you order a free space THz system with housing the sample compartment will enable you to purge the THz beam path with nitrogen - similar as for a TDS10XX system.
  • The options available for the benchtop spectrometer TDS10XX can also be ordered for the pre-assembled spectrometer.
