EVG®720

What is the EVG®720?

The EVG®720 incorporates EVG's SmartNIL™ technology, enabling manufacturing of micro- and nanostructures with high pattern fidelity and minimal residual layer. It's available in manual or automated configuration, with automated cassette-to-cassette handling plus a semi-automated R&D mode, supporting substrate sizes from small pieces up to 150 mm. IES is the official UK representative for EV Group (EVG), supplying, installing, and supporting the EVG®720 for customers across the UK.

How does it achieve fast, high-yield imprinting?

Exposure is achieved using tunable intensity LED lamps, giving fast solidification of a wide range of UV-curable materials and significantly improving throughput. Controlled and smooth demolding, supported by force measurement, ensures high yield and precision throughout the process. The system uses multiple-use polymer stamp technology, with integrated imprinting, UV curing, demolding, and working stamp fabrication in one platform.

What can it be used to manufacture?

The EVG®720 prints large-area nanostructures with high throughput, making it suited to high-volume production of next-generation microfluidic and photonic devices, including diffractive optical elements (DOEs). The platform is open to all commercially available imprint materials and scales from R&D through to production.

How does it keep cost of ownership low?

Designed for low cost of ownership and high efficiency, the EVG®720's multiple-use stamp technology and system housing for process stability make it a practical choice for scaling nanoimprint lithography into production.

Where can I buy or get support for the EVG®720 in the UK?

As EV Group's official UK representative, IES provides UK-based sales, installation, and engineering support for the EVG®720 and the wider EVG nanoimprint lithography portfolio.
*Resolution is dependent on process and template.

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.
