We provide compact and non-compact THz spectrometers that enable high resolution spectroscopic measurements. These systems are based on millimeter wave Backward Wave Oscillators (BWO's) combined with frequency multipliers and broadband Pyroelectric Detectors.

Combining various tuning range of the Backward Wave Oscillators (BWO) with frequency multipliers, these compact and non-compact generators are able to operate in the spectral range of 0.18 to 1.5 THz. Other advantages include compact size, lower operating voltages, extended lifetime and no water cooling required.

Pyroelectric detectors

These detectors are designed for registration of modulated electromagnetic radiation in the mm and sub-mm wavelength range. A black filter can be mounted on the detector input to prevent parasitic illumination in visible and infrared regions.

Golay Cells

We offer essential THz optical components such as Wire Grid & Mid-IR polarizers and holders, polished Picarin & Polyethylene lenses, polished Picarin windows, attenuator sets and low pass filters.

The MS-1.2 magnetic systems come with a 1.2 Tesla permanent magnet designed to house a high-frequency BWO. These systems have inputs for BWO electrical connections and water cooling systems.

The THz imaging systems are computer controlled and employ the high power of BWO based THz generators and the high sensitivity of Golay Cells. These systems provide a scanning range of 2-4cm with high spatial resolution. Two dimensional THz images are obtained by scanning the THz detector/pin-hole assembly.

The TK TeraHertz Absolute Power Meter System is an autocalibrating power meter for use with freespace beams in the frequency range from 30GHz to 3THz. The sensitive area of the System is greater than 30mm in diameter and the System has a typical NEP of about 5uW Hz-1/2.
