The Arcspectro HT is a worldwide unique Fourier transform spectrometer (FTS). It is based on a licensed concept that uses the polarization properties of the light and the optical properties of crystals). It provides a extremely high throughput (sensitivity) and does not need external optics to be used (lens, fibers). The Arcspectro HT is ideal for diffuse reflection measurement and fluorescence spectroscopy. Its ultra compact and robust design maks the device easy to integrate in any application. Its spectral resolution is around 1-5nm at 550nm (depending of the version). Models for VIS and NIR range are available.
