Terahertz Sensors, Components and Systems

Bakman Technologies manufactures the world’s first portable, turn-key, frequency-domain THz spectrometers. Designed for applications beyond the traditional laboratory environment, our spectrometers combine high-resolution spectroscopy with exceptional portability. The PB7300 series of spectrometers weighs only 2.5 kg and can operate for hours using an onboard Raspberry Pi and an external DeWalt battery. These systems can also be paired with our avionics-ready, low-mass THz White cell for extended-path-length, low-pressure gas spectroscopy. Sold worldwide for applications including material characterization, oil analysis, biosensing, and environmental monitoring, our spectrometers were the first frequency-domain THz systems demonstrated aboard a commercially available consumer drone, the DJI S1000.

In addition to complete spectrometer systems, Bakman Technologies designs and manufactures a range of photomixer assemblies for THz generation and coherent detection. Using telecommunications industry-standard packaging practices and precision laser welding, our robust photomixers are designed for demanding applications, including repeated operation at cryogenic temperatures as low as 4.5 Kelvin. Among our specialized products are waveguide-coupled photomixer assemblies that function as tunable THz sources or coherent receivers for applications including sensor calibration, frequency mixing, and detector characterization. These compact, fiber-optically driven devices are particularly suited for integration into cryogenic research systems, quantum sensing experiments, and advanced scientific instrumentation.
