Caesium Iodide -Csl
Caesium Iodide (CsI) is a high-density optical crystal valued for its broad infrared transmission, high refractive index, and excellent scintillation properties. With a typical transmission range from 200 nm to 55 µm, CsI is well-suited for use in infrared spectroscopy, radiation detection, and specialized IR optical systems. At Global Optics UK, we supply precision-machined CsI windows, prisms, blanks, and substrates, with custom sizes, polishing levels, and protective coatings available to meet your application requirements.

FAQ
FAQ
Q: What is Caesium Iodide used for?
A: CsI is used in infrared optics, X-ray and gamma-ray detection, scintillation detectors, and medical imaging systems. It offers excellent transmission in the UV to IR range and strong scintillation properties.
Q: Is Caesium Iodide suitable for IR applications?
A: Yes, CsI has a very broad transmission range (typically from 0.2 µm to 55 µm), making it ideal for infrared and vacuum UV optics.
Q: Is CsI hygroscopic?
A: Yes, CsI is strongly hygroscopic and must be handled in dry environments or sealed properly. Prolonged exposure to moisture can degrade its surface and optical performance.
Q: How mechanically durable is Caesium Iodide?
A: CsI is a soft, brittle crystal with low hardness. It requires careful handling during fabrication and use, especially in uncoated forms.
Q: Where can I find the technical datasheet?
A: You can download the Caesium Iodide datasheet here.
