A curved primary mirror is the reflector telescope's basic optical element Gallery Tutorial TRAIL: Webel SysML Parsing Analysis example: Optical telescopes from Wikipedia: Structure and port-based light flow model Section Slide kind SysML Block Definition Diagram (BDD)
It is free of coma and spherical aberration at a nearly flat focal plane if the primary and secondary curvature are properly figured. Source Wikipedia
A curved primary mirror is the reflector telescope's basic optical element that creates an image at the focal plane [OF THE PRIMARY IF THERE IS NO SECONDARY]. The distance from the mirror to the focal plane is called the focal length. Source Wikipedia
