High Frequency Sensor Development Laboratory


High Frequency Sensor Development Laboratory

World Class Measurement Capability for Frequencies into the Terahertz Range and Beyond

Located on the 4th floor in the Life Science Laboratories the High Frequency Sensor Development facility offers cutting-edge capabilities including a probe station with network analyzer and extenders for measurements up to 1.2 THz, a fourier transform spectrometer for THz/IR spectral analysis of materials, and a tunable pulsed laser operating from 0.8 to 2.5 THz. The lab also includes a variety of auxiliary equipment such as oscilloscopes, spectrum analyzers and power supplies.

We offer training to users to conduct experimentation for use on a fee for service basis to both internal and external researchers, academic or industry based. Following an initial consultation, covering experimental parameters training and access is arranged through the director.
