PicoMaster 100-H

A tabletop direct-write lithography (DWL) mastering tool for the origination of:
 
Security holograms and OVDs
3D holograms and holographic stereograms
Diffractive 'rainbow' patterns
Fresnel lenses
Fresnel images 'bas relief'
Zero colour 'platinum' patterns and images
Other 2.5D, greyscale, optical micro-structures

The PicoMaster-H series is the next generation of mastering systems and the world's first and currently only purpose-built direct laser writers for the origination of security holograms, OVD's, diffractive patterns, Fresnel lenses, Fresnel images, and many other types of 2.5D, greyscale, microstructured optical surfaces.

 

The desktop PicoMaster 100-H offers a complete package to expose all kinds of 2.5D, greyscale, seamless, micron, and sub-micron scale structured surfaces over 110 x 110 mm (4.3" x 4.3") areas. No additional and expensive options are required. The system is supplied with a 405nm laser, 225nm high-resolution mode, professional 4,096 greyscale mode, three software-selectable spot sizes/resolutions, a high-resolution optical auto-focus system, and PicoHLD, a fully-featured, user-friendly hologram, diffractive pattern, and Fresnel lens design and composition program. The system is also supplied with Sitech's Pattern Generator, a program for the generation of random shape and gradient 'pillars of light' patterns for security and packaging applications.

De La Rue is the largest and oldest banknote printer in the world and one of the world's leading security hologram providers. De La Rue recently announced 'De La Rue has been on the cutting edge of advanced Benton rainbow (classical) holography since the 1990s and we continue to evolve our portfolio, most recently introducing a direct-write micro-lithographic imaging platform, which enables new, distinguished, bold effects.’

PicoMaster directly written gratings and features 

PicoMaster profiles

Unlike micro-lithography, which requires an array of optical components, single-beam direct-write lithography creates seamless, non-pixellated, noise-free, and distortion-free holographic gratings and other micro-features.
