Diffractive Optical Elements




NIL Technology are specialized in diffractive optical elements (DOEs). We make diffractive optics that are customized to your specific needs. This enables you to efficiently shape light and to consequently improve the overall performance and flexibility of your products.









4 levels, fused silica, 500 nm pixels, 500 nm step height






Cross-section of replication in polymer (device) with steep side walls, sharp corners and low roughness








Why choose NIL Technology to make your DOEs?

NIL Technology offers you diffractive optical elements that are customized to your specific needs. We have made diffractive optics for many years and have extensive experience in complex and high precision DOEs.
With design, manufacturing and optical characterization all within NILT we can offer rapid turnaround times for our customers.
Through high accuracy in the manufacturing we are able to reach high performance optics. Some of the benefits of our DOEs include:
  • High definition/pattern fidelity
  • High aspect ratios
  • Steep side walls
  • Multi-levels
  • High resolution
  • Low roughness



PreciseWe have high-quality production methods and years of experience with high-precision diffraction structures
AdaptableEasily replace or combine refractive optics with diffractive optics
Energy-efficientShape and divide laser beams to control intensity
Custom-madeCustomized to your specific needs and specifications
EffectiveBe able to precisely control the phase across the aperture and make complex intensity

With NILT, you can expect improved diffraction efficiency and better stray light suppression, among other key benefits. Contact us to get an overall understand of how it will affect your optical applications and product performance by working with NIL Technology.
