Scintillation Crystals

Scintillation Crystals

Our NaI(Tl) scintillation crystals come with a wide range of customization options to meet the needs of your company, project or institution.

NaI(Tl) (sodium-iodide doped with thallium) scintillators are a highly price-effective solution for radiation detection as they provide excellent light output and a wide energy detection range with low costs. We grow our scintillation crystals in-house at our factory, allowing for quick delivery and optimized compatibility with our scintillation detector assemblies and electronics.

Technical specifications
