HOLOSTAR, 3D-Lab and the Holocom / Holopress Group are specialized in the production of holograms for industrial purposes. Starting with the origination of technical, industrial or artistic holograms in small runs we also cover years of experience in holographic mass production.
We offer a wide collection of sophisticated holographic film (diffraction-foil) which can be printed and converted with your artwork.
Itīs also possible to rent or purchase unique holograms or whole collections.

Holography History
Holography has been developed in theory by Prof. Dennis Gabor in 1948. Gabor is said to be the inventor of holography (Nobel-Prize 1971), although he could not proof his invention because the laser was not invented back then. The invention of the first laser in 1960 enabled the varification of Gaborīs theory in 1964 at the University of Michigan by Emmett Leith and Juris Upatnieks "just out of curiosity", the world´s first laser transmission hologram of a 3-D object was created:

First laser transmission hologram
by Leith / Upatnieks 1964
In 1962 Dr. Uri N. Denisyuk in the USSR created a combination of holography and Gabriel Lippmann's work of true-color photography (Nobel-Prize 1908), resulting in the first white-light hologram viewable under "normal" white light.
How is a hologram made?
In the meanwhile many different types of holograms exist, so we reduce to the basic technique of holographic mastering. (simplified statement)
During the production of a holographic master a special holography-laser is used, functioning as a light source. The exposure is made in a lab using a holographic master-table. The laser beam is divided into 2 halfbeams using a beamsplitter. (object beam + reference beam).
After expanding the object beam with a lens it illuminates the object. Both halfbeams meet again in the holographic master (film) and create an interference pattern. This interference holds the 3-dimensional information of the object, just as viewing the object through the master plate. The photochemical development of the master makes it viewable the first time under laserlight.
This original, so called H1 (Hologram 1) can be copied to a white light hologram or any kind of hologram.
Even today the production of a master is a big effort. You need special equipment and experience. During exposure any kind of vibration, noise or even temperature differences have to be completely avoided, hence otherwise the interference won´t occure and you just see nothing. Therefore even specialists often need several tries to expose the master as intended.
Hologram Types
The most important hologram types nowadays are:
Whitelight Transmission Holograms
Whitelight Reflection Holograms
Photopolymer Holograms
Dichromate Holograms
Embossed Holograms
Applications
The use of holographic products increases rapidly worldwide. The most important applications are:
For holographic mass production also photopolymer holograms are used. The main part are embossed holograms still, since they are the most cost efficient application.
Embossed Holograms can be supplied as:
Self-adhesive Labels / Stickers
Hotstamping Foil
Security Holograms
Tamper evident, self-destroying when peeled off
Holographic metallized paper/ cartonstock
