Diffractive Optics

Diffractive optics based on micro- and nanostructured surfaces offer flexible possibilities to present new optical functions which are often barely achievable with conventional optics. This opens up new areas of application for optics.


  • Electron beam-lithography
  • Laser beam-lithography

Our offer

  • Optical and mechanical design specific to the application
  • Technology advisory and production of customized elements
  • Optical and profilometric characterization of element functions
  • Production of prototyps


Diffractive micro and nano optics are applied to particular gratings for spectroscopy applications, for example:

  • Astronomy,
  • Compression of ultra short laser pulses,
  • Computer generated holograms for the inspection of highly precise aspheres,
  • Fresnel lenses and lens arrays for the homogenization of illuminations,
  • Diffractive filter structures,
  • Structured polarizer,
  • Optics with complex features (even applicable to curved surfaces).

Our quality policy

The core competencies of the working group CMN-Optics, as part of the Fraunhofer Institute for Applied Optics and Precision Engineering IOF, contain the development and production of photonic micro and nanostructures, which are being significantly pushed forward on behalf of customers and external partners.

Our philosophy is to optimally support our customers in the selection of our processes within research and development as well as pilot production. We would like to offer optical components that comply with the latest technologies and add value for the customer. Customer satisfaction is always the focus of our efforts, whereby this can only be achieved through complying with high quality standards, as well as a trustful contact to the customer. Meeting agreed deadlines and services enjoys our highest priority. Securing the technological and economical basis follows a continual advancement of processes technological equipment, constantly striving for leadership in innovation and quality in our field of activity.

In order to embed the standards of quality among staff, a quality-promoting attitude is being conveyed to all employees of the CMN-Optics group, as the quality of our products is the responsibility of each individual employee. Thereby, the working group’s management explicitly supports openness concerning problems, questions, and discrepancies related to the QM-system, so that all employees are able to contribute to the development and improvement of the QM-system.

The certification in accordance with DIN EN ISO 9001 underlies that we actually live our quality policy, in order to meet the challenges of our customers.
