太赫茲波(THz)又被稱為“生命光線“,是“光“能量的一種,是指波長(zhǎng)在3μm到1000μm之間,頻率為0.1-10THz,介于微波與紅外線之間的電磁波。太赫茲波不僅擁有與光相同的直進(jìn)性,還具有與電波相似的穿透性和吸收性。

We make your analysis easy and efficient –for research and industrial use. Photonics West
2014 PRISM-AWARD winner terahertz spectrometer from HÜBNER provides you new opportunities in many fields of analytical measurements.
The T-SPECTRALYZER was designed for quick set-up and for routine measurements in everyday analysis tasks. Only a mains connection is required to make the system ready to use without further infrastructure. Due to latest technology, the terahertz spectrometer does not require any additional cooling or external gas supply. This ensures a costeffective operation.
Individual expansion modules and an intuitive user interface support recording, processing and exporting your measurement results. Thanks to the touchscreen based user-friendly operation no time-consuming Within a few seconds the non-destructive and contact-free analysis of your samples is done. Full automation of your measurement process allows for extensive data sets to be taken without high personnel costs. Its standardized hardware and software interfaces seamlessly integrate the spectrometer into your existing network and process flow.
Customized solutions are available on request.
