Description

Fiber-coupled Terahertz Spectrometer T-FIBER, offered by Ekspla, features flexible and robust design. It has integrated femtosecond fiber laser with two fiber output ports. Comparing to common Ti:S oscillators, fiber lasers are smaller, cheaper, more reliable and feature parameters that are perfect for terahertz generation. Femtosecond laser, delay line and signal registration electronics are integrated in a single compact housing with footprint only 40×40 cm. Minimal set of free space optics used in spectrometer allows stable long time operation. Special “no bearing” design of fast delay line makes its lifetime practically unlimited. Delay line allows real time data acquisition with 10 spectra/s speed and 110 ps time window.

Fiber-coupled THz emitter and detector make switching between experiment geometries easier than before. Due to its compact size and reliability during transportation, T-FIBER spectrometer is dedicated for laboratory use as well as for real field applications. We are also happy to customize it according to special OEM customer requirements. Basic setup of T-FIBER spectrometer includes optical rail, with fiber-coupled THz emitter, detector, two PE lenses and sample holder. This setup provides transmission geometry and it is extremely simple in alignment. As an option goniometer stage can be supplied. This inexpensive module allows operation in multiple most common geometries, including transmission and tunable angle reflection from approx. 18.5° up to 90°. It also can be used for unique THz scattering experiments, because sample and detector angles can be changed independently. This module gives also better focusability of THz beam and better dynamic range of THz signal.
