Application

Cesium Bromide is extensively employed in infrared optical components due to its broad transmission range (0.2–55 μm). It serves as a scintillation material in radiation detection and X-ray imaging systems. Researchers also use CsBr in photonic devices and as a precursor for cesium-based catalysts in organic synthesis.
