Oil‐Repellent Optics for Wastewater Sensor Applications

A fundamental issue for the identification of environmental problems is the early detection of chemical water pollutants. To guarantee reliable measurement results and to reduce maintenance costs, soiling of the sensor surfaces should be minimized. This work presents a method for fabrication of optical and oil‐repellent functional surfaces, realized by combination of statistically produced nano‐roughness with adapted…

New Process Chain for the Production of Complex Freeform Optical Components

Freeform optics enable completely new solutions in optical design for many different optical applications. Complex optical systems usually need a variety of multiple classic spherical surfaces to fulfill their function. The usage of a freeform surface instead makes it possible to replace some of these spherical surfaces by only one freeform element. Therefore, it is possible to build optical systems that are more compact and lighter …

Non‐Contact Measurement Brings Decisive Optimization

The intervals at which production efficiency in optics need to be streamlined are getting shorter and shorter, due to the fast pace at which optical device technology is moving forward. Companies need to know their breaking point. Organizational stress testing becomes essential for economic survival in the global business arena. A small but important aspect of production improvement can be achieved by opting for non‐contact…

Towards a Fully Integrated Lab‐On‐A‐Chip

The identification of pathogens in body fluids is important for proper treatment of infections with antibiotics. Besides the pure identification of the pathogen’s species, however, its antibiotic profile can be crucial with regard to their resistance to certain drugs. By the use of DNA‐based microarrays, multiple of such parameters can be measured at the same time, e.g., by fluorescence imaging. Before the optical…

No More Sunburn

A UV‐LED based system was developed that allows to determine the sun protection factor (SPF) of sunscreen lotions in a non‐invasive way in vivo. This method is faster and reduces the medical risk for the test subjects …

Mobile Microscopy and Automated Image Analysis

Mobile microscopy and automated image analysis are powerful techniques for many applications. A mobile system that consists of a smartphone, an optical attachment and automated image recognition software in a cloud laboratory and its current and possible future applications are described in this article. The idea is to create a very fast, cheap, location‐ and knowledge‐independent system for many use cases. …

Multiphoton Tomography for In Vivo Skin‐Age Determination

Nothing represents our age better than our most outer layer: the skin. But the age of the skin may differ from the person’s chronological age due to a complex interplay of external and internal factors. A non‐invasive method to determine the skin age on a microscopic level in vivo is clinical multiphoton tomography which allows for direct non‐invasive imaging of biological tissue with subcellular resolution. …

Measurement Technology

Optical Metrology of Freeforms and Complex Lenses

Optical surfaces are becoming more and more complex and custom designs increasingly involve freeform surfaces and discontinuous geometries. This article discusses requirements and limitations of optical form measurements as part of the manufacturing process of such extreme optics.

Microdisplays for Smart Eyewear

Human‐machine interfaces determine how machines serve humanity and in what form information is provided. This can take the form of the label on a simple light switch. However, it can also be a highly complex control console with countless monitors and computers in an industrial facility.

The Largest Eye That Humankind Has Cast into the Heavens

The resolution of earthbound telescopes can be improved by large primary mirrors, which can only be realized as segmented mirrors. In order for these giant mirrors to maintain their form despite the wind load and the effect of gravity, their individual segments require stiff drives that work with a large travel on the one hand and allow nanometer‐precise positioning on the other. So‐called hybrid drives that combine a…
