Paper Abstract

The 6.5m MMT telescope currently has three focal configurations. The f/5 optical configuration has a system of optical baffles to prevent stray light from entering the focal plane. The system consists of a cone baffle supported on the secondary (M2) structure and set of concentric rings suspended between the secondary and the primary (M1). This paper reviews the optical configurations, mechanical design, alignment, installation, and measured performance of the system.
