Optical Design
High precision Masters
Fast Prototyping & Replication
Manufacturing of optical parts

We develop solutions for advanced optical high-tech components, focusing on sensors, imaging and displays, where flat optics provides a competitive advantage and we assist our clients in all aspects from idea, to proof of concept, prototyping and mass production.

We enable future optical solutions for Smartphones, Augmented Reality, IoT, Automotive, and in addition we serve the biotech and space industries among others.

Optics & Photonics Excellence

Diffractive Optical Elements
- High accuracy (CD down to 20nm), multiple levels (up to 64), up to 8-inch wafers, made to customer specifications
Blazed Gratings
- Flexibility and precision, down to 200 nm period, low optical loss due to small anti-blaze, low surface roughness (RMS < 2nm)
Slanted Gratings
- High uniformity, flat bottom of the trench, tuneabletapering, low roughness (RMS < 2nm), distinct shape
Large Area high-precision gratings
- Accuracy in grating periodicity across large areas (stitching < 11nm), non-periodic gratings are possible
Microlens Arrays
- High accuracy spherical and aspherical MLA
Meta-surfaces
- Complex nano-sized patterns for meta-materials

NILT Solutions

Optic Design

NIL Technology provides cutting edge optical components for sensors, 3D imaging and displays
Using both commercial software and internally developed algorithms to design and simulate performance of:
- Diffractive Optical Elements (DOE)
- Meta lenses
- Microlens Arrays (MLA)
- Regular gratings and slanted gratings
We provide optical design to match specific optical needs.

Mastering

NILT manufactures masters with micro- and nanostructures in Steel, Nickel, Fused Silica and Silicon.
With proprietary manufacturing processes we make full use of high end CMOS equipment such as JEOL9500 e-beam and DUV steppers to simple mask aligners and an arsenal of etching equipment to produce masters with patterns ranging from multi level structures for diffractive optics, to slanted gratings and micro lens arrays.

We choose the right process for the right application at the right cost

Prototyping

Manufacturing method depending on component
NILT is working with in-house replication with hot embossing, UV-imprint, roll2roll and injection moulding
Wafer level prototyping
Short cycle time from idea/concept to testing of optical performance
Easy transition from prototyping to high volume manufacturing

Volume Manufacturing

Flexibility depending on device type
In-house manufacturing
Manufacturing Partners
The manufacturing makes use of our high-quality state-of-the-art masters
Manufacturing setup is scalable from small to large volumes

Strong Operations

We have profound technical understanding of nano-lithographic processes and manufacturing know how
Fabrication in five state-of-the-art silicon processing cleanrooms
Very versatile and large cleanroom equipment selection
Working across different nano-replication manufacturing platforms (nanoimprint, injection moulding and Roll-2-Roll imprinting)
Proprietary processes

NILT was established in 2006 and is a privately-owned high-tech SME, based in Denmark and with offices in Sweden and Switzerland. The company has a large and diverse customer base and has served more than 400 different customers globally. In December 2018, NILT raised 6.3 M EUR in financing co-led by Jolt Capital and NGP Capital.
