LAV produces a broad range of ultraviolet visible and infrared optical thin films.

Depositing on optical surfaces single or multiple layers of metallic and/or dielectric materials, with different reflactive index and with thickness defined by the theory, it is
possible to modify the spectral characteristics (reflection, trasmission and polarization) of the optical component, in a predetermined way.

Application’s fields of LAV coating are: optical devices, measurement analytical, medical and astronomical instruments,
photo, film cinema and television technologies, night vision, laser optics, UV, VIS and /or IR contrast enhancement and protection systems, control lighting technologies, decorative and protective utilization, masks production for etching technology.
