Laser interference lithography (LIL), hidden image holograms, 2D-3D holograms, rainbow holograms

The service provides original hologram fabrication in light sensitive recording media forming sub-micrometer size dimensional variable relief structures (or variable refractive index structures) for document security and brand authentication. Holograms are recorded using the physical object (model) or computer graphics supplied by the customer. Three-dimensional holograms (3D), 2D/ D holograms, hidden image holograms and combined hologram of high degree of protection recording are fabricated using optical tables, optical-mechanical components, controls, lasers and other devices. Combined hologram recording can be made by combining: a) 3D electron beam lithography with 2D/3D holograms, b) dot-matrix holograms with 2D / 3D holograms, c) 2D/3D holograms with hidden image holograms and so on.

Optical document security measures and their production technologies and research

We can make products from stickers (in many different shapes of self-decaying seals) to difficult optic changing holograms. We do: projecting holographic signs and manufacturing of original; manufacturing of metal stamp; micro relief on metal polymeric band; making an adhesive layer and cutting holographic sticker in shape you need. Products are made in high technologies: interference holographic lithography, electronic nano–lithography, optic micro lithography, vacuum and electrochemical covers and other modern equipment and technology.
