Light-Shaping Surface - The surface geometry redirects light to create images
Proprietary software is used to calculate and design a surface geometry that will redirect passing light in a way that produces a clear and highly detailed light image on a nearby surface. The light effect is known as “caustics” and you have probably experienced it as patterns on the table when sunlight passes through a wineglass.
The surface geometry is replicated on exclusive watches, jewellery, beverage bottles, and perfume flacons which projects logos and images. It can also be used as an anti-counterfeiting measure that is difficult to replicate.
The technology works with any direct light source such as sunlight or light from a flashlight. The surface geometry is shallow and therefore difficult to see or feel. It works with all transparent materials and it is also possible to design surface geometries for reflective materials. The technology is patented and available under license.

You get the transparent plastic plate seen on the image. You can project the image of the sample onto a surface with a flashlight.

QUESTIONS & ANSWERSAsk a Question
How do I go about customising this if I would like to take this forward?
The information card that is attached to the sample includes contact information for the supplier. The supplier can calculate the light-shaping surface geometry from a photo you supply. They can also help you find a manufacturer who can create the tooling you need to produce products with the surface.
