DEVICE FOR PERFORMING FIELD-ASSISTED ION-EXCHANGE IN PLANE-PARALLEL PLATES

In plane-parallel plates, zones of increased refractive index are to be produced as optical waveguides or the like from a salt melt by means of ion exchange. For this purpose, the plate (42) is clamped in between two holding bodies (10,12) of metal. The holding bodies (10,12) form, on either side of...

Zusammenfassung:	In plane-parallel plates, zones of increased refractive index are to be produced as optical waveguides or the like from a salt melt by means of ion exchange. For this purpose, the plate (42) is clamped in between two holding bodies (10,12) of metal. The holding bodies (10,12) form, on either side of the plate (42), cavities (26,28) which are open towards the plate. The cavities are surrounded by closed sealing surfaces (30,32) which bear against the plate (42). Stock vessels (18,20) for salt melt are connected via filling lines (34,38) to the lower ends of the cavities (26,28). Vent lines (36,40) start from the cavities (26,28).
