The demand for bendable sensors increases constantly in the challenging field of soft and micro-scale robotics. We present here, in more detail, the flexible, functional, insect-inspired curved artificial compound eye (CurvACE) that was previously in

This presentation discusses a collaborative effort of two Fraunhofer institutes to develop a lithography model that simulates the fabrication of blazed gratings using grayscale lithography. The model is calibrated with experimental data of blazed gra

Snapshot multispectral imaging is a rising non-invasive and contact-free analysis method and technology to discriminate or identify objects based on their spectral characteristics. We demonstrate a versatile system approach for compact and real-time

We describe the design and set-up an array of micro-spectrometers for parallel sensing. The approach utilizes a prism – grating combination to obtain a linear light path and to achieve a high packing density. This yields 2’000 micro spectrometers

We developed a novel LED projection based direct write grayscale lithography system for the generation of optical surface profiles such as micro-lenses, diffractive elements, diffusors, and micro freeforms. The image formation is realized by a LCoS m

Stochastic subwavelength structures on polymethylmetacrylate (PMMA) surfaces were produced by low-pressure argon/oxygen plasma treatment. The modified surfaces show antireflective properties exhibiting low scattering losses depending on the size and

The combination of a 10.6 μm main pulse CO2 laser and a 1064 nm pre-pulse Nd:YAG laser in EUV source concepts for HVM would require collector mirrors with an integrated spectral purity filter that suppresses both laser wavelengths. This paper discus

In this study, a miniature artificial compound eye (15 mm in diameter) called the curved artificial compound eye (CurvACE) was endowed for the first time with hyperacuity, using similar micro-movements to those occurring in the fly's compound eye. A

Resonant grating waveguide structures are discussed as extreme narrow-band reflection filters. Their spectral response may shift due to environmental impact, e.g. from temperature, pressure or humidity, making it interesting for sensor applications.
