| Spectral Range – 0.06 THz to 3 THz (2 cm-1 – 100 cm-1)
| Transmission module accepts standard infrared (IR) sampling accessories
| ATR modules for optimized measurements on as little as 1 mg solid sample
| Solid-state emitter and detector for ambient temperature operation
| Bespoke optics casing with controlled alignment optics for system optimization.
Product description
TPS Spectra 3000 from TeraView is the world’s first commercial terahertz spectrometer capable of performing both transmission and attenuated total reflection (ATR) measurements.
Based upon TeraView’s proprietary semiconductor-based, terahertz pulsed technology, TPS Spectra 3000 yields superior analytical performance – all while operating under ambient conditions.
TPS Spectra 3000’s modular sample compartment accepts standard IR sampling accessories for transmission measurements.
ATR modules provide non-destructive measurements of solids, suspensions, slurries pastes and gels. ATR measurements are obtained from as little as 1 mg of solid sample.
TPS Spectra 3000 offers enhanced flexibility to investigate intermolecular hydrogen-bonding vibrations, crystalline structure lattice vibrations or low-frequency internal vibrations without concern for thermal effects.
