About This Webinar
The presentation will discuss the Fourier Transform Infrared Spectroscopy (FTIR) advantages of selected types of beamsplitter, including Potassium Bromide (KBr), Zinc Selenide (ZnSe), and Cesium Iodide, and the use of each material for further resolution and spectral scan lengths. In addition, specific beamsplitter coatings critical to the instrument performance will be covered during this session.
FTIR is a technique that uses the absorption of infrared energy to establish an infrared fingerprint of chemical compounds. The system typically uses an interferometric technique that scans the infrared spectrum and passes that spectrum through a sample compound. The vibrational modes of each compound can be studied using the absorption of the infrared energy. Known for its high resolution and high sensitivity, FTIR relies heavily on accurate and precise beamsplitters that offer broad transparency in the infrared region.
