The direct laser writers with ultimate resolution

PICOMASTER is a series of direct laser writers that work with a single laser beam to create high-resolution structures. The versatile, low-maintenance laser writer provides best-in-class resolution for features and grating periodicity. The user-friendly PICOMASTER series provides the perfect solution for your laser lithography challenges.

With features such as:

  • Single focused beam writing strategy
  • Down to 0.3 μm resolution
  • 4096-level grayscale lithography
  • Proprietary autofocus even on challenging substrates
  • Up to 8” x 8” exposable area
  • Stitch-free exposure

PICOMASTER direct laser writers offer the perfect solution for your microfabrication needs.

With 405 and 375 laser sources available, a resolution of 300 nm is guaranteed, so that  PICOMASTER direct laser writers produce the highest resolution available in the market. Enhancing innovation strength for scientific and industrial purposes, these maskless direct laser writers unlock unique opportunities for R&D in photonic devices, microelectronics, MEMS, 3D lithography, optical variable devices (OVD), diffractive optical elements, and many more.
