The Raith Laser Systems (formerly 4PICO) 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, computer-generated holograms, diffractive patterns, Fresnel lenses, Fresnel bas-relief' images, micro-mirror and micro-lens arrays, and many other types of 2.5D, greyscale, micro-structured optical surfaces.

The PicoMaster 150-H offers a complete package to expose all kinds of 2.5D, greyscale, seamless, micron and sub-micron scale structured surfaces over 150 x 150 mm (6" x 6") 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 Spatial Imaging's Pattern Generator, a program for the generation of random shape and gradient 'pillars of light' patterns for security and packaging applications.
