Hyperspectral antireflective coatings AR-plas2®

Antireflection coatings AR-plas2® for the 380 nm to 2500 nm spectral range can be produced on an industrial scale. A silica nanostructure on the outermost surface of the coating guarantees a low residual reflectance for a broad range of light incidence angles and a high transmission from the ultraviolet to the infrared spectral region. Coatings AR-plas2® exhibit a high temperature and humidity resistance. They are especially suitable for curved optical lenses in camera systems.

Additive manufacturing of optical freeform mirrors for VIS-NIR-IR applications

An entire process chain for the additive manufacturing of metal mirrors and -modules out of AlSi12, AlSi40, and Al6061 is developed, enabling the processing of substrates up to Ø 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 optics of Ø 170 mm exhibit high stability and stiffness along with surface roughness of < 1 nm RMS and form deviation of < 150 nm PV after post-finishing.

Atomic layer deposition of interference multilayer systems

Conformal coatings are enabled by atomic layer deposition (ALD). This coating technology, which is broadly applied in semiconductor industry, is based on surface reactions of precursor molecules at the substrate or growing thin film. It allows precise thickness and composition control on arbitrarily shaped optics and micro/ nanostructured components. Interference multilayer systems such as antireflection coatings, dichroic mirrors and bandpass filters are presented
