the einkristall is a material characterized by a completely regular structuring of atoms throughout the crystal. besides its optical qualities, einkristall has extremely valuable technical properties. its usage is indispensable in a number of modern technologies, such as micro electronics and information technology. among other things, einkristalle are used in crystal spectrometers - spectometric measuring instruments - that utilize the reflection of crystals in order to separate radiation components.
