NANO-STRUCTURES

Applying nano to mega

Micro- and nanostructures applied onto very large areas in high volume.

From small to tiny, from micro to nano

Everybody knows what a lens can do. It can focus light, it can magnify the image of an object. Basically, it manipulates light to achieve a certain purpose. Now imagine thousands of tiny lenses, indistinguishable by the naked eye, packed together in a thin layer on a surface. That is what we call a micropatterned light management layer. If you would shrink these micro lenses further, you end up with nanostructures that manipulate the light in a completely different way. These layers with micro- or nanopatterns can benefit various types of products, from solar panels to 3D displays.

Next to optical effects, micro- and nanostructures can affect many other properties, for example the way a surface feels, how a water droplet runs off it or how air flows over it.

 

 

 

 

 

 

 

Structures

Structures with dimensions from 500 micrometer down to 50 nanometer can be imprinted with the Morphotonics nanoimprint technology. Patterns can be random or periodic; a few examples:

  • Pyramids, cones
  • Lenses, lenticulars
  • Fresnel lenses
  • Prisms
  • Diffractive nano textures
  • One dimensional and two dimensional gratings
  • Moth-eye textures
  • Anti-Reflection (AR) textures

 

 

 

 

 

 

Images of our micro- and nanostructures

 

From one to many copies

We start with a master with your structure. Often these master shims or molds are made from nickel, but we can also work from other metals or even polymers. With this master we can start a duplication process with different generations.

Depending on polarity (inverse or not), requested markers or edge lines we can choose to use positive or negative copies from a suitable generation to make the flex stamps to be used in our roll-to-plate process. In any case, it only takes one master to end up with many flex stamps. In turn, each flex stamp can be used many times (>1000x) to make structured products.

Making a master: from small to large area

Your nano- or microstructures are originated on a master (the original).  If you do not have your own master, Morphotonics has a network of partners who can originate any of these structures according to your requirements with techniques like laser interference lithography, laser writing, laser ablation or diamond cutting. Morphotonics also has a library with micro- and nanopatterns. Perhaps we already have the structure you are looking for.

If this master does not have the size suitable for your application, Morphotonics can help to scale it up to large sizes. By UV-tiling parts with your desired and optimized structure together, the patterned surface can be increased up to 1*2 m2.

 

OUR TECHNOLOGY

nanotechnology morphotonics icon

Nanotechnology

Micro- and nanostructures can enhance the photonic properties of a surface. We develop and apply a large range of micro- and nanostructures for all kinds of applications.

Roll-to-plate nanoimprint

Our roll-to-plate (R2P) technology uses an advanced reusable flexible stamp and can be used for imprinting structures on small and large surfaces.

Flex stamps

We create stamps for the roll-to-plate imprinting process. The flex stamp is used as a masterfilm and rolled into the resin to fabricate the patterned product.

Research & Development

Our engineers gladly work together with you to develop the best textures, stamps, samples, imprinting tools and materials for your application
