Optipur® - uncover the invisible

Optipur® materials are inorganic compounds for the production of single or monocrystals. These materials are of the highest purity and particularly well suited for single crystal growth.

Can the invisible be visible?

Owing to the high purity, Optipur® materials are specifically suited for the production of single crystals as used in demanding optical applications or for medical imaging in scintillators.

As an example, Optipur® sodium iodide (NaI) and cesium iodide (CsI) are widely used to grow single crystals for the production of detector plates in medical imaging. These crystals are typically doped with thallium iodide (TlI), which we offer in beaded form for improved handling and reduced safety risks.

The Optipur® portfolio consists of (mainly) metal halides, which are available as anhydrous powders or in beaded form for immediate usability and easy handling.

Product features:

  • High purity
  • Anhydrous powders or beads
  • Mainly metal halides
  • Immediate usability and easy handling
  • Special packaging for hygroscopic materials

Applications for Optipur®

  • Medical imaging (x-ray, SPECT,…)
  • Radiation detection (scientific, security,…)
  • UV optics
  • IR optics

Technical Information

The purity of each production batch is strictly controlled with careful attention paid to impurities that have an influence on transmission, light scattering, or scintillation efficiency. Hygroscopic materials are typically vacuum-dried at high temperature and are packaged for dry storage.

As a DIN/ISO-certified material supplier, we offer a seamless documentation flow and traceability, as well as standardized CoAs for each production batch.
