ABSTRACT:
Zones having an increased refractive index shall be created as optical wave guides, or the like, in plane-parallel plates by ion exchange from a salt melting. For this purpose the plate is clamped between two holding hodies made of metal. The holding bodies form cavities (26,28) on both sides of the plate. These cavities are open towards the plate. The cavities are surrounded by closed sealing surfaces engaging the plate. Reservoirs for the salt melting communicate through filling conduits with the lower ends of the cavities. Vent conduits extend from the cavities.
