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:

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
