Compact Nanoimprint Tool – CNI

CNI v2.1 edition

A desktop nanoimprint tool, for easy replication of micro- and nanoscale structures.

The starting point for nano-replication

The CNI is a compact nanoimprint tool that can be used for imprinting and hot embossing. It allows for replication of micro- and nanostructures from a master to a substrate. The CNI tool can perform both thermal replication and UV replication.

The tool is available in a 100 mm version that supports masters and substrates up to 100 mm diameter, and a 150 mm version that supports thermal processing on masters and substrates up to 150 mm, and UV processing of masters and substrates up to 200 mm diameter.

The CNI tool is the perfect starting point for nanoimprint, but it also supports mature and advanced development work. The CNI tool is simple to operate, it is robust and facilitates non-standard processes and new experiments.

Technical requirements at installation site

  • Compressed dry air or nitrogen pressures of 6-11 bar with outer diameter Ø 6 mm connector. Flow should be at least ½ standard L/min
  • Vacuum better than 0.1 mbar in Ø10 mm outer diameter connector (if you want the full benefit of the vacuum option)
  • Power of 110-240V (50-60 Hz, larger than 200 W)


  • The compact nanoimprint tool shall preferably be installed in a clean, dust- and particle free environment to achieve an optimal result
  • Operating temperature range: 10°C to 35°C
  • Operating humidity range: 30-70%


  • Pressure booster: If your lab cannot supply at least 6 bar of compressed air pressure, NILT can provide a pressure booster that will double 3-5 bar to 6-10 bar.
  • Vacuum: NILT recommends the Welch PK2DC oil-sealed rotary vane vacuum pump or the Welch MP101 V dry diaphragm vacuum pump to use with the vacuum option. Any other pump with similar or better specs should work as well.
