Setup notes / Optical assemblies
An optical assembly combines geometry, alignment and the properties of its materials.
Describing the setup
Aperture limits the bundle of light entering a system.
Open reference →Reading the first observation
Alignment changes should be recorded consistently.
Open reference →Working with variation
Reflections depend on angle and surface treatment.
