Diffractive Optical

The manufacturing process for optical security products refers to several and different advanced technologies.

A pioneer in holography and optical sciences applied to visual security devices, SURYS has developed unique optical technologies. Based on interferential microlithography and digital holography, these techniques enable etching of optical microstructures and nanostructures onto areas of micrometric dimension, with no pixelization. Using a combination of thin reflective coats offers countless possibilities in terms of design, a high-level resolution and unique aspects and effects.

Mastering optics, galvanoplasty, chemistry, vaccum coating, demetallization, coating, laser engraving, etc., is key in the production of high security technologies.

Volume holograms & photopolymer

Volume holography techniques, also known as reflection holography, combined with the performances of the photopolymers, a photosensitive polymer, provides exceptional -close to 100% diffractive efficiency- holographic imagery.

Applications are in the HOE’s (Holographic Optical Elements) and security DOVID’s.

Our team, at SURYS Research has 40 years of experience in volume holography and ae reconized world experts in this science.

OVD role

The main role of the OVD is to provide a visual authentication function.

Control levels

OVD's are organized in several levels of authentication with no or specific tools.

Originations

Origination refers to the different optical image format each based on specific technology, providing a specific visual security effect
