KRs-5 (TlBr-TlI) is a gorgeous red crystal commonly used for attenuated total reflection prisms for IR spectroscopy. It is also used as an infrared transmission window in gas and liquid sample cells used with FTIR spectrophotometers in place of Potassium Bromide (KBr) or Cesium Iodide (CsI) for analysis of aqueous samples that would attack KBr or CsI optics. It has a wide transmission range and is virtually insoluble in water. It is a useful alternative to AgCl since it is not photo-sensitive and for ATR applications it will transmit well beyond the 18 micron useful range of ZnSe. <\/p>\n<p>Background on FT-IR:<br \/>\n<a href=\"https:\/\/en.wikipedia.org\/wiki\/Fourier-transform_infrared_spectroscopy\">wikipedia<\/a><br \/>\n<a href=\"pics\/IR200\/FTIRintro.pdf\">Nicolet brochure<\/a><\/p>\n<p>Unit with case removed:<br \/>\n<img decoding=\"async\" src=\"pics\/IR200\/IMG_5542.jpg\" alt=\"\" \/><\/p>\n<p>IR mirror on the left.
