During the production of functional laser optics as well as for the development of innovative products in the optics industry it is necessary to precisely determine the purity of optical materials.
The need for preciseness and sensitivity has increased extremely, especially for optimized materials of high quality. These materials include various quartz glasses, crystals and numerous other optical glasses, which also serve as carrier materials for quality coatings.
In order to determine the optical quality of laser optics, the Laser Zentrum Hannover e.V. (LZH) has developed a laser calorimeter which is able to measure the absorption of light in the material. Specific advantages of the device are its high sensitivity, absolute calibration and a wide spectral range of the test wavelength.
The laser calorimeter is industrially available at the LZH in customer-specific versions. Also, the LZH offers services for absorption measurements for a great variety of laser beam sources for various industrial applications.Contact:

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
