We provide a large volume of optical devices, e.g. holographic optical elements, waveguides, or lab-on-a-chip solutions. Based on our HoloPrint® nanoimprint lithography technology at Stensborg, we offer industrial-scale volume production of a variety of nano- and micro- topology surfaces, specializing in high capacity productions based on Roll-to-Roll (R2R) and Roll-to-Plate (R2P) manufacturing.
Examples of volume productions Stensborg has delivered:
Diffractive optical elements
Diffractive optical elements (DOEs) are optical elements that are made of micro- or nano-scale structures and are used for modulating and transforming light in a predetermined way. They have multiple applications in for example gratings, lenses, filters, lasers, and holograms.
Optical waveguides are a special type of DOEs for low-loss guidance of light. These waveguides are the essential optical components for augmented and mixed reality (AR/MR) in goggles and screens as well as ultrafast and ultrahigh bandwidth telecommunication and computing.
Holographic optical elements
Holographic optical elements (HOEs) are optical elements that are produced by using holographic imaging processes. Due to their ability to implement various optical functions in a single flat device. Today, HOEs are used in a range of applications; some typical holographic optical element-based applications are projection screens, data storage, head-mounted displays, lens arrays, and solar concentrators.
Optical security devices
Optical Security Devices are used by governments as well as many industries and can be found on various identification cards, banknotes, secure documents, and on branded gods and media to protect against counterfeiting, protect copyright, and provide tamper evidence features. Stensborg has decades of experience in the production of machinery and chemistry to produce Optical Security Devices, and we welcome discussing your needs.
Optical filters for photovoltaic cells
Stensborg has experience manufacturing advanced optical films for solar (photovoltaic, PV) cells, for instance, we have manufactured filters for coloring cells, transparent cells, and flexible surfaces.
Advanced 3D structures for microfluidics
Mass manufacturing of microscopic structures for microfluidic applications in the health sector is another of Stensborg expertises. Our manufacturing equipment is based on a rolling production line, which has a special cost advantage in manufacturing in large volumes of Point-of-Care testing devices.
One step before upscaling
If you are at an early stage of your development process and first need to experiment and characterize the structural properties of your design, the HoloPrint® uniA6 DT could be the right starting choice for you. The HoloPrint® uniA6 DT unit allows fast iterations of the development cycle by quickly producing a new design in small batches, so it is a perfect tool for rapid prototyping. The desktop imprinter enables you easily to experiment with imprinting process parameters like velocity, pressure, and light intensity, as well as, choice of light-curing resin materials.
