The Rubin Observatory Simonyi Survey Telescope consists of 3 aspheric mirrors: an 8.4-m primary mirror M1, a 3.5-m convex secondary mirror M2, and a 5.0-m tertiary mirror M3.

The primary and tertiary mirrors, which were coated on April 27, are fabricated from a single piece of glass.
The secondary mirror (M2) is the largest convex mirror ever made.
Field of view = 3.5°.
The 3.2-gigapixel camera hangs below the secondary mirror.
