'Solder Bumping' Could Keep Lenses Fixed in Space

The issue with optical devices in space is that the extremely low pressure determines the adhesive that keeps them in place to release gases that either contaminate the lenses or move the lenses a couple of microns out of their original setting place. The same effect can be obtained while subjecting the adhesive material to high temperatures of lasers in the ultraviolet wavelengths. The answer given to this problem by the Fraunhofer Institute for Applied Optics and Precision Engineering IOF i... Read »
