The owner-managed family company KORTH KRISTALLE GMBH is producing precision optics in single and series production for more than 70 years.

At our Kiel site, we grow crystals from high-purity molten salts. We offer a variety of crystalline materials including fluorides and other halides, oxides, glasses and semiconductors.

In our in-house optics production, our crystals are processed into optical components using modern and conventional polishing methods.

Our product portfolio covers the entire range of the light spectrum (VUV-FIR) and includes optical windows, spherical lenses, prisms, beam splitters, mirrors, filters, special optics with holes, wedges, steps. All optics can also be coated on request.
