EVG®720

The EVG®720 system incorporates EVG’s cutting-edge SmartNIL™ technology, enabling the manufacturing of micro- and nanostructures with exceptional pattern fidelity and minimal residual layer. Exposure is achieved using tunable intensity LED lamps, providing fast solidification of a wide range of UV-curable materials and significantly improving throughput. With controlled and smooth demolding, supported by force measurement, the EVG®720 ensures high yield and precision in every process. This system is capable of printing large-area nanostructures with unmatched throughput, making it an ideal solution for high-volume production of next-generation microfluidic and photonic devices, including diffractive optical elements (DOEs). Designed for low cost of ownership and high efficiency, the EVG®720 with SmartNIL™ technology is the optimal choice for the future of nanotechnology production. (*Resolution is dependent on process and template. 

Features:

• Proprietary SmartNIL® technology with multiple-use polymer stamp technology
• Integrated imprinting, UV curing demolding, and working stamp fabrication
• Automated cassette-to-cassette handling plus semi-automated R&D mode
• Optional top-side alignment
• Optional mini-environment
• Open platform for all commercially available imprint materials
• Scalability from R&D to production
• System housing for best process stability and reliability

Applications:

• Diffractive Optical Elements (DOEs) / Optics / Photonics        
  Manufacturing periodic or quasi‑periodic nanoscale structures for wavefront shaping, gratings, beam splitting, diffractive lenses, optical filters. The full-field imprint and high fidelity make it appropriate.
  
  
• Microfluidics / Lab-on-a-Chip        
  Imprinting micro- and nanoscale channels, features, surface textures in polymer layers; useful due to its ability to pattern large areas and conform to non-ideal surfaces.
  
  
• Meta-surfaces / Metastructures / Nanophotonics        
  Creating arrays of sub‑wavelength features for manipulating light (e.g. metasurfaces for lenses, beam steering, color, polarization).
  
  
• Bio‑/Medical Devices        
  Patterning of nano-/micro‑structured surfaces for cell interaction, bio-sensing surfaces, micro‑arrays, etc.
  
  
• Micro- & Nano-Optics for AR/VR / Waveguides        
  Imprinting optical waveguides or surface diffractive structures used in displays, augmented reality devices, micro‑optical elements.
  
  
• Prototype / Pilot Production of Nanopatterned Surfaces        
  Because the EVG 720 supports automation and throughput, it is useful not only for R&D but also small volume manufacturing of devices requiring nano-scale patterning.
  
  
• High Throughput Nanopatterning        
  The integration of imprinting + curing + demolding enables continuous or semi-continuous workflows, reducing handling steps and increasing throughput.
