    摘要： A simple and economical method is described for compacting or shrinking flat glass panes. The method ensures high temperature homogeneity in the glass. First, the glass panes are cleaned and then a stack of glass panes to be treated is assembled without applying a release agent to any of the glass panes. Then the stack of glass panes is placed between ceramic panels made of silicon-infiltrated silicon carbide and this stack together with the ceramic panels is subjected to a heat treatment in a radiation furnace at temperatures ranging from 300° C. to 900° C. The ceramic panels have a thermal conductivity, which, in the region of the heat treatment temperature, is at least 5 times as large as that of the glass panes. The ratio of the total thickness of the ceramic panels to the height of the glass stack should be at least 1/&lgr;/40W/(mK), wherein &lgr; is the thermal conductivity of the ceramic panel at the temperatures of the heat treatment.

    摘要： a method and to an apparatus for producing optical glass elements, in particular for producing what is referred to as low-cost optics for focusing light onto small areas, for example, for photovoltaic applications or optical couplers. The method for producing the optical glass elements includes: providing a glass rod having a selected cross-section, heating the glass rod such that it can be deformed in at least some sections, molding at least one optical glass element from the deformable section using a molding tool, separating the optical glass element from the glass rod at the connection, arranging a plurality of separated optical glass elements to form a group, and grinding and/or polishing at least one section of the separating surfaces of the grouped optical glass elements. The invention makes it possible to produce optical glass elements that meet low quality requirements in high quantities and with high output at low cost.

The doped fiber must at least approximate the formula: ##EQU1## in which n.sub.o means the refractive index of the matrix material and r.sub.i =i.multidot..DELTA.r. A process for the production of the single-mode optical fiber is disclosed using at least 100 layers.
