VerTera continuous-wave terahertz extension

In addition to the VERTEX 80 v transform infrared performance and flexibility of verTera upgrade extend version can also realize single wave number range, or the top technical parameters such as high spectral resolution.Generally need to use the radial heat meter of liquid helium temperature is reached.VerTera can also be implemented:

• Integrating the most advanced cw THZ technology
• Spectral range extended to 3 cm - 1 (< 90 GHz)
• Unique and effective spectral resolution < 0.0007 cm^{- 1}(< 20 MHz)
• Fourier transform infrared spectroscopy and share sample storehouse and terahertz optical accessories
• Vacuum environment and advanced terahertz science calculation method, ensure the best performance of terahertz
• Fourier transform infrared spectroscopy and terahertz attachments are by powerful OPUS software control

Advanced cw THZ technology:

VerTera used the high-precision semiconductor optoelectronic mixer, converting near-infrared laser terahertz radiation.The light source and detector has been integrated into the VERTEX 80 v optical path, the level of the near infrared (NIR) laser radiation by optical fiber and vacuum sealed lead connection.

Terahertz through vacuum environment to achieve the best performance

Vacuum environment can significantly reduce the unnecessary atmospheric disturbances, while providing excellent stable state, in order to achieve better performance of terahertz.

Unique terahertz data processing to achieve the highest resolution:

The extraction of traditional shock photocurrent signal extremum method will greatly damage spectral resolution.And verTera only through a unique algorithm can obtain more effective spectral resolution (< 0.0007 cm - 1 < 20 MHz), and the use of terahertz step length.

Different verTera version:

VerTera extension has three different versions to choose from, facilitate you get different spectral range, this all have achieved better than 0.0007 cm - 1 (20 MHz) spectral resolution.Summary of current version, please see the table below.VERTEX 80 v by room temperature component, under the mode of FTIR, seamless coverage is beyond the scope of a given limit spectrum.

No element can be realized at low temperature limit of terahertz spectrum:

Bolometers is a proven and as low as 5 cm - 1 the high sensitivity of terahertz detectors, however, it requires the use of liquid helium, this increases the cost, but also for the operating personnel with professional knowledge, because of scarcity, even cannot be used in some areas.And pulse tube cooling Bolometers alternative cooling components such as the price is very expensive, is also likely to produce adverse vibration of cooling time for several hours.Using verTera extension pieces, you just need to press a button, everything was done, it will not produce a large number of operating costs, but also can realize more excellent spectrum limit and resolution.
