Far Infrared Spectrometers

Sciencetech manufactures grid polarizing beam-splitters for use in the far-infrared and terahertz spectral regions. These beamsplitters divide the incoming beam according to its polarization. The beam-splitter consist of very fine parallel aluminum lines spaced 4 µm apart on a thin mylar substrate. It has the widest spectral range with a higher frequency cut-off than that of other polarizers that work in the near-millimeter wavelength range.
This particular model is 3" (7.5cm) diameter, and is the middle size of the IR beam-splitter polarizer Sciencetech offers. For larger or smaller sizes, or for a full list of technical specifications, please speak with your authorized Sciencetech technical sales staff member.

This option allows the SPS-300 to use both output ports simultaneously. The internal mirror that directs the parallel beam to the converging output is replaced by a large beam splitter which sends half the radiation to the converging output, and the other half to the parallel output.

Please discuss any questions you have regarding the beam splitter, or operating two detectors simultaneously, with your authorized Sciencetech technical sales staff.

The optional external light source port upgrade provides both a motorized turning mirror and the flange for the input port so that users can couple external light sources (e.g. glowbar, Gunn diode, synchrotron) into the SPS-300. The motorized mirror switches inputs between the SPS-300 internal mercury lamp and external light source. Additional optics and chambers may be required to focus the external light source into the SPS-300.

This option includes all the components necessary to reach micro-Torr vacuum, including gauges, ports, valves, and both a roughing and turbo pump.
If only milli-Torr levels of vacuum are needed, please purchase the "SPS 300 Standard Vacuum Operation" upgrade instead.

This includes all the necessary parts for vacuum operation including seals, valves, gauges, and port covers, as well as a roughing pump capable of reaching mTorr vacuum. The SPS-300 itself is capable of maintaining higher levels of vacuum operation, but requires a turbo pump in order to reach those levels of vacuum.
For higher vacuum operation (up to micro-Torr applications), please purchase the "SPS 300 Ultra-High Vacuum Operation" upgrade instead, as it includes all items listed here in addition to a turbo pump.

The standard SPS-300 has a 50mm translating stage, wich can provide resolution up to 0.12 wavenumbers. The high resolution upgrade option extends the translating stage to 300mm, allowing the SPS-300 to achieve a resolution of 0.020 wavenumbers. Due to the increased stage length, an extension to the vacuum-sealed body is needed to accommodate the extra distance.

The most powerful TeraHertz FTIR available in the mid and far IR Range, the SPS-300 is our second generation Martin-Puplett/Michelson Interferometer designed and built at Sciencetech's own facilities in London, Canada. With a wide variety of optional upgrades and components to suit any research application, the SPS-300 has been successfully used in Material Research, Biomedical, Medical, Astronomy, Aerospace, Superconductivity, Security, Defense and a wide range of other fields by distinguished customers including the European Space Agency (ESA), the National Aeronautics and Space Agency (NASA), the Max Planck Institute, the Argonne National Labs, The Canadian National Research Council, the Brookhaven National Lab, L'Institute d'Astrophysique Spatiale, Lawrence Berkeley National Lab, and many universities the world over.

The instrument is designed for research applications and therefore features special hardware and software designed to allow the use of samples under many different research environments (High Vacuum, High & Low Temperature, High & low Pressures, High Magnetic fields, etc...) and conduct sensitive and fast "Rapid Scans" with the mirror moving continuously as the detector collects data. Sciencetech also supports the researchers with the design and manufacturing of custom made coupling devices and sophisticated sample chambers to meet specific needs.

Please contact your authorized Sciencetech technical sales representative to discuss how we can build a FTIR designed for your technical specifications.
