VTT MLI / CLI - Lenses
MLI (horizontal) or CLI (vertical) lenses are amongst the most used secure elements in the market of governmental documents. Fine lenticular lenses with a radius as little as a few microns are manufactured to perfect precision to match each customers requirements. These lenses can be produced intended in the plate or raised above the plate’s surface to maximize flexibility.
During the personalization phase, each MLI or CLI is then laser-marked with flipping, unalterable card holder information, making it impossible to forge the document.
