Abstract

There is a need for further work in characterizing and selecting spectrally selective coatings in two areas for ground-based telescope. The first is in low-emittance coatings for upper-end telescope and baffle structures. Low-emittance coatings are necessary to prevent overcooling of telescope structures relative to the ambient air temperature. The second area where more work is needed is the area of baffle coatings for infrared instruments. Detailed work is needed to evaluate which coatings are best suited for these applications and whether commonly available coatings such as anodized aluminum and commercially available paints are adequate for these applications.
