Reducing Mirror Seeing Problems in Meniscus Mirrors
Abstract
It is well known that telescope seeing is worsened when temperature differences exist between the primary mirror and the air above the surface. The author describe a new mirror blank configuration that enables mirror blank temperature control sufficient to substantially eliminate mirror seeing through liquid cooling. Thermal properties and manufacturing feasibility have been studied.
