Germanium/Zinc Sulphide (Ge/ZnS) single and multilayers are deposited by ion assisted electron beam deposition on Silicon substrates for applications in the 2-15 µm wavelength region. Refractive indices of Ge ZnS thin films extracted from measured reflectance transmittance spectra. Several types mid-infrared filters (high-, anti-reflection coatings dichroic filters) with a number layers ranging...

We have synthesized and analyzed by mid-infrared reflectance spectroscopy silicate glasses that are representative for the on surface of Mercury. The glass compositions based high-pressure laboratory experiments resulting phase. spectra interest investigating Mercury using MERTIS (Mercury Radiometer Thermal Infrared Spectrometer) instrument board ESA/JAXA BepiColombo mission. Both powdered frac...

Small and compact mid-infrared devices are of increasing importance, as there several applications demanding on-site real-time measurements in harsh real-world scenarios. The RobustATR, an innovative infrared attenuated total reflectance (IR-ATR) accessory, has been developed tested with exemplary analytes integrating a single-wavelength Fabry–Pérot quantum cascade laser light source for testin...

This Letter presents field-based evidence of the perturbing effects of surface anisotropy on the remote sensing of burned savannah. The analysis is based on bidirectional spectral reflectance data collected at different solar illumination angles and convolved to Moderate-resolution Imaging Spectroradiometer (MODIS) reflective bands. Results from a grass savannah site show that burning reduces t...

The spectroscopic properties of an electrochromic cell in the mid-infrared and near-infrared regions have been investigated. Absorption modes due to moisture were found to hinder the performance of the device by absorbing in the frequency range 3000 cm to 4000 cm. A method was developed to remove water from the cell by paying careful attention to the creation of the electrolyte gel. This electr...
