Stensborg is a privately held company located in Denmark.They are experts in nanoimprinting lithography solutions.
For more than 20 years, they have delivered optical designs, mastering tools, and volume production to our clients and partners at universities and organisations within the private and government sectors.
Each year, they develop exciting new ways to control and interact with light and matter and keep pushing this technology to new limits, further and further around the globe.
Take a look at our technology to see what we do and our latest project, a desktop NIL product we call the HoloPrint® uniA6 DT. Or, if you are interested in learning more about some of the custom-made designs.
Roll-to-Roll is a popular method for volume fabrication on flexible materials; metal, paper, and polymers,including thin glass.
Traditionally nanoimprint lithography (NIL) is derived from a quartz or glass wafer plate-against-plate process technology.
At Stensborg, they have developed our own unique and patented nip moulding process (HoloPrint®), designed for nanoimprinting on transparent and opaque materials. This approach works to avoid costly and undesirable web coatings.
The Roll-to-Roll machine, typically employing several rollers, has various coating techniques; dip coating,knife-over-edge coating, slot-die coating, direct- and micro-gravure coating, inkjet and spray coating.
Roll-to-Plate nanoimprint lithography is an imprinting process that consists of a roller mechanism and a rigid surface plate.
The core of our roll-to-plate fabrication unit is a transparent cylinder that houses an Optical Engine in the centre - method shown below.
Our NIL imprint template is mounted onto the cylinder to nano pattering the light-curing resin that feeds into the machine. Shortly after the NIL imprint template is in full contact with the resin, the resin will enter the curing stage in the nib.
Our approach to Roll-to-Plate is a three-stage process; Contact, Cure and Demould; which all occurs in the nip.
Smart And Affordable Technologies
Our HoloPrint® uniA6 DT is affordable, portable and easy to use.
This HoloPrint® desktop unit is suitable for small-scale nanoimprint lithography work. This device is ideal for fast prototyping, testing, and characterisation of the property of a structure, which includes work with photo-curable resins and imprinting materials.
The typical applications range from imprinting, lab-on-chip to diffractive optical elements, and other nano-imprinted structures. The HoloPrint® uniA6 DT works within its protected environment.
