Capabilities

Eksma Optics is a manufacturer, not a reseller. Coating, polishing, lens manufacturing, metrology and assembly are all owned and operated by us in Vilnius — 100% vertical integration from raw material to finished, certified optic.

That control is what lets us quote custom optics quickly, hold tight tolerances, and keep quality consistent across serial OEM production. From flat-optics blanks to coated assemblies, every stage happens under one roof and is measured before it ships.

Eksma Optics cleanroom — operator at an optical coating machine

Five manufacturing capabilities under one roof

Each department feeds the next — flat-optics blanks become CNC lenses and coated substrates, then aligned assemblies, all measured and traceable.

Optical coating deposition chamber

Optical coatings & IBS

Custom coatings designed and deposited in-house, with quick-turnaround IBS capacity.

  • IBS, IAD & e-beam deposition
  • AR, HR, dielectric and metallic coatings
  • High-LIDT laser coatings; absorption <1 ppm achievable
  • UV–IR coverage, custom spectral design
Flat-optics polishing machine

Flat optics manufacturing

From raw blanks: cutting, rounding, grinding and final polishing on single- and double-side machines.

  • N-BK7, UVFS, Infrasil, Suprasil, CaF₂
  • Single- and double-side polishing
  • Substrates for mirrors, windows, polarizers, filters
CNC lens generating line

CNC lens manufacturing

Spherical and aspherical lens production on CNC generating and polishing lines.

  • CNC generating & polishing
  • Centering to tight tolerances
  • Prototype to serial volumes
Interferometric metrology bench

Metrology & quality control

Every part measured — interferometer and spectrophotometer per piece, with certificates on request.

  • Interferometric surface testing
  • Spectral & transmission measurement
  • Environmental durability & First Article Inspection (FAI)
  • Full end-to-end traceability
Optomechanical assembly bench

Assembly & integration

Optomechanical assembly and aligned optical subsystems — components or finished modules.

  • Mounted & bonded optics
  • Aligned beam-delivery modules
  • OEM-ready subsystems

Materials we process

N-BK7 Suprasil Infrasil Nonlinear crystals
UV fused silica Sapphire CaF2 ZnSe
Schott Glass Heraeus Glass Ohara Glass

One continuous, traceable process

Raw glass and crystal come in one end; measured, coated, assembled optics go out the other.

Vertical integration you can build a program on

Owning every step removes supplier hand-offs — shorter lead times, tighter quality control, and the ability to scale a custom part into serial OEM production.

100% Vertical integration
7300 m² New facility, >1000 m² ISO 7 cleanrooms
40 years Manufacturing expertise
λ/10 Surface flatness capability
100% Parts measured & traceable
