Crystal Growth – Customized Optics
Korth Kristalle founded in 1949 is specialized in the field of crystal growth and the manufacturing of optical components. The company is family owned and independent, a unique situation in Europe. This allows us to be flexible to meet our customer requirements. We can produce any quantity from a single crystal up to industrial volumes.
Typical Applications are e.g.:
- Analytical instruments
- Environmental protection
- Space technology
- Laser and Medical technology
Our Products and Services include:
- Optics in all different inhouse* materials:
- ((high-end synthetic MgF2, CaF2, BaF2, SrF2, LiF, KBr, NaCl, KCl, CsBr, CsI, KRS-5)* – also Sapphire, ZnSe, ZnS, Ge, Si, Quartz and others))
- Spherical Lenses
- Plano Optics
- Beamsplitters
