This is a technical drawing/engineering specification document for an optical component, specifically a gold-coated optical surface, created for Ernest Orlando Lawrence Berkeley National Laboratory (LBNL). The document provides precise dimensional and surface treatment specifications for a rectangular optical component with multiple technical requirements. Key specifications include:

Dimensional and Surface Details:

• Total length: 500 ± 1 mm
• Width: 85 ± 0.2 mm
• Gold-coated optical surface with a tangential radius of curvature
• Optically polished surface with a tangential neodal radius
• 16 [63] finish for machined surfaces per ASME standards
• Gold-coated optical surface with specific tolerances
• Clear aperture region defined by hatched area
• No machining or marking operations allowed after polishing

The drawing includes a permanent mark per specification, with precise location and character requirements, and specifies chamfer and edge treatment standards. The document is officially released by the LBNL Document Control Center on February 12th, 2025, with an authorization key of IG6WJW6O28.
