- Singulation process of diffractive optical elements.
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
- 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:
- 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).
