Company Description

EKSMA OPTICS is a manufacturer of precision optical laser components, used in lasers, laser systems and in other photonic instruments. We have proven experience providing custom solutions and also offering a wide range of catalogue products for the fast off-the-shelf delivery.

The product range includes optical components, dielectric thin film coatings, DKDP, BBO and KTP electro-optical Pockels cells, laser and nonlinear crystals, optical systems, opto-mechanical mounts, motorized stages and tables. Components cover a wavelength spectrum starting from the UV (193 nm) through VIS to IR (20 μm) and the terahertz (1–5 THz) region.

The EKSMA Optics polishing facility specializes in the polishing of flat optics made of BK7, UVFS, Infrasil and also DKDP, LBO, and ZnGeP2 crystals whereas high quality precision polished faces are required for high power laser applications. Company also owns CNC grinding and polishing facility manufacturing spherical and aspherical lenses, as well as IBS coating facility.

EKSMA Optics is an ISO 9001:2008 certified company.
