TDS10XX

The benchtop THz spectrometer TDS10XX is easy to use and meant for laboratories where material characterization shall be performed in the THz region. The spectrometer comes with an internal sample compartment (which can be purged with nitrogen) or external fiber-coupled antennas. Both setups can be used to conduct transmission and reflection measurements with a collimated or focused THz beam. The TDS10XX is controlled via USB using a laptop with the pre-installed T3DS software package.

The following optional features are available:
  • SHR - Sample Holder for Reflection measurements
  • SHA - Sample Holder for Attenuated total reflection measurements
  • SHF - Sample Holder for Fiber coupled antennas
  • FSU - Fast Scan Unit with maximum scan rate of 100 Hz
  • IU - Imaging Unit for fiber coupled antennas
  • T2T - Theta-2-Theta angular scanning unit for fiber coupled antennas
  • 2FCA - 2 additional Fiber Coupled Antennas

TDS10XX data and price information

The performance and the price of the spectrometer depend on the femtosecond laser used and the chosen configuration. The best results can be achieved using a 800 nm laser source (TDS1008) and the internal sample compartment with a nitrogen purge.

Optional parts for TDS10XX

The measurement capabilities of the THz spectrometers listed above can be extended by additional devices.

> SHT - Sample Holder Transmission


The sample holder transmission consists of a plate, two sleds with focusing THz lenses, one adapter for large samples (at least 30 x 30 mm) with collimated THz beam and one adapter for small samples (at least 10 x 10 mm) with focused THz beam.
The SHT comes with the base structure and every TDS system.

> SHR - Sample Holder Reflection


The sample holder reflection consists of a plate, two sleds with focusing THz lenses, one adapter for large samples (at least 30 x 30 mm) and one adapter for small samples (at least 10 x 10 mm). The angle of incidence or the SHR is 30° by default.
The sample holder for reflection measurements requires the base structure that comes with the sample holder transmission (SHT) and every TDS system.

> FSU - Fast Scan Unit


The Fast Scan Unit is used to change the laser beam path with a frequency of a few Hz in order to get a real time picture of the THz signal. It is typically used as an extension to simplify the signal optimization. Due to the limited scan range and time resolution it cannot be used to collect data at the same quality as with a slow scan measurement. However, the much faster data acquisition allows to change the optical or THz beam while watching the signal live.
