SC906: Introduction to Visible and NIR Spectrograph Design and Development for Astronomy
This course provides attendees with an introduction to aerial spectrograph design and development for astronomy. The course covers the optical fundamentals that constrain spectrograph design; various components that make up a spectrograph for astronomy; and the various system configurations for different applications along with the associated performance analysis. The course includes several design examples including a group-based design project whose goals are to develop a first-order spectrograph design given a set of astronomical constraints and then to determine the specific design parameters for each component that would be given to a lens designer to complete a detailed design. Specific concepts to be addressed include: image quality, throughput, flexure, performance modeling and system testing.
