Concentrating and Directing Light Precisely to Where it is Needed

Light-emitting diodes save energy. In terms of their light output, however, they have so far been unable to compete with light bulbs. A new, low-priced optical component is set to change that situation: It concentrates the light and directs it precisely to where it is needed.

Soldering Optical Components Instead of Gluing

Lenses in optical devices are kept in place by adhesives. This can cause problems when the microscopes and cameras are employed inside a vacuum, as the adhesives may release gases that contaminate the lenses. One alternative is to solder them instead.
