Abstract

We are developing a meniscus coating process for manufacturing large-aperture dielectric multilayer high reflectors (HR's) at ambient conditions from liquid suspensions. Using a lab- scale coater capable of coating 150 mm, square substrates, we have produced several HR's which give 99%+ reflection with 24 layers and with edge effects confined to about 10 mm. In calendar 1993 we are taking delivery of an automated meniscus coating machine capable of coating substrates up to 400 mm wide and 600 mm long.
