Features

  • >6 THz Bandwidth in <5 s
  • >100 dB Peak Dynamic Range
  • Versatile, Scientific THz Time-Domain Spectroscopy (THz-TDS) Workhorse
  • Automated Measurements and Data Transfer via Network
  • Synchronizable to External Laser Source (e.g., for ASOPS or External Pump Laser)
  • Options Include:
    • Multiple THz Channels
    • Multi-Color Laser Outputs: 780 nm or 1560 nm
    • High-Resolution Option: <0.7 GHz with 1600 ps All-Optical Delay Scan Window

The TERA-K15 fiber-coupled terahertz spectrometer provides a complete solution for fast broadband time-domain THz spectroscopy, offering a high degree of flexibility for scientific THz applications.

The system includes Menlo Systems’ latest figure 9® femtosecond laser source with a 1.5 μm emission wavelength; a fiber-coupled optical light path with a delay line; a THz light path with a THz emitter, THz detector, and TPX THz optics; control electronics; and a PC with data acquisition and evaluation software. The delay line covers a standard scan window of >850 ps, enabling a high spectral THz resolution of <1.2 GHz. Customers can also opt for a longer scan window of >1600 ps, which enables spectral resolution of <0.7 GHz. The dual detector option supports simultaneous measurements in transmission and reflection geometry. For THz imaging applications, our TERA Image extension unit can be integrated into the setup, alongside the image acquisition and reconstruction software.

Included Components

Optical Components Measurement and Control Electronics
  • Integrated ELMO Femtosecond Laser Source
  • Integrated FIber-Coupled Optomechanical Delay Line
  • External Fiber-Coupled THz Emmiter and Receiver Modules (TERA15-FC)
  • THz TPX Polymer Lens-Based Optical Beam Path
  • Data Acquisition Platform
  • Integrated PC and Software Package for Measurement and Data Analysis
  • TCP Socket Remote Control Interface
