TOU Prototype Design and AIV Concept

! The document details the design and assembly, integration, and verification (AIV) concept of the PLATO Telescope Optical Unit (TOU) prototype. It outlines the optical and mechanical design adaptations for the prototype, aiming to replicate the final TOU structure while addressing cost and schedule constraints. The AIV process emphasizes the precise alignment of lenses and the testing of the prototype's optical performance under varying conditions. This approach facilitates validating the assembly and alignment procedures, ensuring the prototype meets the required specifications for the PLATO space mission, focused on studying exoplanets and stellar oscillations
