Hologram copiers - Geola - lasers and holography experts


3D Hologram copiers Holographic printer, or HS studios can manufacture a limited number of 3D holograms. In order to speed up hologram manufacturing process, Geola Digital uab has invented a new hologram copying method and now offers the hologram copying systems.

Working principle

We have noticed that all holographers were using a wrong contact copying scheme when master exposure is done by slit-shaped laser beam radiation. As it is shown on the picture below - if the width of slit is narrow, mostly noise is recorded on hologram copy instead of master hologram image.

We have modified an usual contact copying scheme as it is shown below. In our contact copying geometry, all master hologram image interferes with reference beam - as a result no noticeable noise is recorded on hologram copy. This contact copying scheme was patented by Geola Digital in 2007. Same contact copying geometry also is suitable for Denysiuk type hologram manufacture.

Geola's contact copying scheme

Our standard hologram copier incorporates Geola pulsed RGB laser, but we may be able to supply you a hologram copying system incorporating the laser which wavelengths will match your master holograms replay wavelengths.
