MULTI-LAYER OPTICAL COMPONENTS AND METHOD FOR FABRICATING SAME

摘要

A multi-layer mirror comprising a front plate, a backing plate and spacers coupled between the front plate and the backing plate. The spacers are closely packed with one another and arranged in a manner where adjacent spacers contact one another and packing spaces are defined between groups of spacers in contact with one another. Each of the spacers comprises a plurality of ventilation holes extending between a bore of the spacer and an exterior of the spacer. For each spacer, the plurality of ventilation holes comprises a first ventilation hole in fluid communication with a first packing space defined at least in part by the spacer and a second ventilation hole, spaced apart from the first ventilation hole and in fluid communication with a second packing space defined at least in part by the spacer.

1. A multi-layer optical component comprising:
a front plate; a backing plate; and a plurality of spacers extending between the front plate and the backing plate to maintain a space therebetween, the spacers arranged in a closely packed arrangement where each spacer is in contact with at least one neighboring spacer; each spacer comprising a bore-defining surface which defines a bore that extends through the spacer and between the front plate and the backing plate; and each spacer provided with a plurality of spaced apart ventilation holes for providing fluid communication between the bore of the spacer and a location exterior to the bore of the spacer.
