The Fiber-Coupled THz-Spectrometer


T-SPECTRALYZER F is a Plug & Play THz-Spectrometer that facilitates non-destructive and contact-free analysis of your samples.

Individual measurement modules and an intuitive user interface support the recording, processing and exporting of your measurement results. T-SPECTRALYZER F is a high-performance THz-Spectrometer offering the frequency range 0.1 – 2.5 THz and a dynamic range of up to 54 dB*.

Short measurement times of 0.05s allow the monitoring of processes or spatial mapping of your samples. The operation is user-friendly – no time consuming training is required. The standardized hardware and software interfaces help you to integrate the spectrometer into your existing network and process flow. No safety precautions are necessary as terahertz waves are completely safe.
