Material analysis and qualification

For design and manufacturing

With your individual needs in mind, various materials are used to achieve optimal results, from concept to the prototype phase all the way to volume production.

In order to satisfy the extraordinary demands of the product’s properties, these materials must comply with the highest requirements and be adapted to your needs. To do so, we employ a number of different processes to analyze and qualify materials:

Our analysis processes include

  • Various microscopy technologies
  • Ultrasound testing technology (scanning acoustic microscope)
  • X-ray fluorescence spectrometers
  • Electric measurement technology (incl. oscilloscope, high resistance meter, LCR bridge)
  • Measurement and work area in climatized clean room (ISO 6 equivalent)
  • Testing facility for long term and service life tests
  • Material testing machine
  • Materialography (separation, embedding, sample preparation)
  • Diverse spectral measurement technologies combined with coating expertise

Material analysis

Materials are tested with regards to various physical, chemical, mechanical and technological characteristics.

Service life tests

The service life is estimated many times over using tests under amplified testing conditions. This allows to achieve results within a short time that are used to calculate product safety.

Damage analysis

Nevertheless, should something break, we employ various microscopic and analytical procedures to determine the cause.

Metrology for prototype design and manufacturing

We measure, what we manufacture.
We make use of extensive measurement techniques and develop individual measurement setups in order to ensure that our optical components, assemblies and systems comply with your specifications. We create own software to measure customer-specific parameters.

Information about the various methods for material analysis and service life tests can be found under the section Material Analysis.

Wavefront measurements

We employ various highly precise interferometers (up to λ/20 WF PV) to characterize the flatness of optical surfaces as well as wavefront deformations in reflection and transmission. We possess many years of experience in optimally adapting measurement tools and processes to your product. For example, we can conduct measurements in vertical or horizontal testing configurations or take measurements in a clean room or vacuum. Optical surfaces undergo testing using in-house interferometers during the manufacturing process.

Imaging Performance

Modulation Transfer Function (MTF)

A large MTF system with a maximum aperture of 200 mm is available to measure imaging quality. In addition to MTF measurement, further characteristics like distortion, field of curvature and focal width for field angles > 90° can be measured. Object and image positions are finitely and infinitely adjustable in wide areas.

Measurement Technology Design

For special demands not included in our standard processes, we develop customer- and application-specific testing areas that allow automatic evaluation using specially adapted software. Our testing processes are the result of close cooperation with the optical design experts and consider the possibility of actively adjusting optical elements in order to guarantee optimum product quality.

This allows us to achieve the performance limits that are physically possible.

Depending on the product and needs at hand, the performance limits physically possible are met and maintained in many cases.
