The manufacturing process for optical security products refers to several and different advanced technologies.
Pioneer in holography, Hologram. Industries has developed some unique optical technologies. Based on interferential microlithography and digital holography, these techniques enable etching of optical microstructures on areas of micrometric dimension, with no pixellization. A combination of slim reflective coats with those technologies offer countless possibilities in terms of design, a high level resolution and unique aspects and effects.
Mastering optics, galvanoplasty, chemistry, metallization, demetallization, coating, laser engraving, etc...is key in the production of high security technologies.
