The Fraunhofer Institute for Applied Optics and Precision Engineering IOF develops innovative optical systems to control light from the generation to the application.
Our service range covers the entire photonic process chain from optomechanical and optoelectronic system design to the manufacturing of customized solutions and prototypes.
The institute works in the five business fields of Optical Components and Systems, Precision Engineering Components and Systems, Functional Optical Surfaces and Layers, Photonic Sensors and Measuring Systems and Lasers.
Additive manufacturing of optical high-power components for VIS-NIR-IR applications
An entire process chain for the production of, e.g., customized lightweight metal mirrors out of AlSi12, AlSi40, and Al6061 is developed, enabling the processing of substrates up to ∅ 230 mm by selective laser melting. Due to the lightweight design with stochastic or symmetric structures, a mass reduction of up to 75% is achieved. Manufactured mirrors of ∅ 150 mm exhibit high stability and stiffness along with surface roughness of <1 nm RMS and form deviation of <150 nm PV after post finishing.
Antireflection coatings AR-plas2® for glass and plastic lenses
New organic-inorganic hybrid materials enable the manufacturing of antireflection coatings AR-plas2® for the 300 to 1500 nm spectral range on an industrial scale. A refractive index lower than 1.1 on the outermost surface of the nanostructured coating guarantees a low residual reflectance for a broad range of light incidence angles. Coatings AR-plas2® exhibit a high temperature and humidity resistance. They are especially suitable for strongly curved optical lenses.
Stable polarization entangled photon source for quantum key distribution
Space suitable Entangled Photon Sources provide the basis for quantum communication. The hybrid and simple, but highly efficient source of polarization-entangled photons is based on a Sagnac Interferometer and spontaneous parametric down-conversion in bulk periodically poled potassium titanyl phosphate crystals, which is pumped by a 405 nm laser diode at 5 mW. More than 300.000 photon pair events per second are detected, while maintaining overlap fidelity with the ideal quantum state of 0.98.
