Caesium Iodide - CsI

Click here to download PDF version of this page.

A very useful material with a transmission range from the visible region out to 70 microns through to a 2mm thick window. CsI is very soft and water-soluble and when humidity is relatively high polished surfaces may be damaged by moisture in the atmosphere. Principally used for Infrared Spectroscopic windows and also for beam splitters in FTIR Instumentation. CsI is also available thallium doped for scintillation applications.
