TeTechS’ terahertz measurement kit is used by researchers to custom build their terahertz time-domain measurement setups. Complete with the highest quality components such as a Toptica femto-second laser and TeTechS’ photoconductive antennas, the kit allows for optimal realization of transmission and reflection measurement configurations. This selection of components has been extensively tested and designed to save researchers time and money while also providing them with the flexibility to choose the right set of components to fit their specific measurement needs.
The kit comes complete with two TeTechS T-Era photoconductive antennas, enabling researchers to achieve new levels of low noise performance among terahertz sources and detectors and ultimately achieve superior system dynamic range and discrimination.
TeTechS’ T-Era series terahertz photoconductive antennas are used to generate and detect electromagnetic waves at the terahertz frequencies for imaging, spectroscopy and sensing applications. T-Era chips are made on ultra-fast and highly-resistive low-temperature grown GaAs semiconductors and are packaged inside patented enclosure designs, making the chips superior in performance and easy to use. TeTechS’ T-Era photoconductive antennas achieve new levels of low noise performance among terahertz sources and detectors, to achieve superior system dynamic range and discrimination. T-Era series terahertz photoconductive antennas allow researchers and technologists to build their own terahertz spectroscopy and imaging measurement setups with superior performance and revisit their scientific and technological problems under the light of terahertz waves.
TeTechS’ air-coupled T-Era series terahertz photoconductive antennas are used in the measurement kit to generate and detect terahertz waves.
