hubblewebblightpath
Both Hubble (top) and Webb (bottom) are reflecting telescopes. Light from distant objects enters the telescope, reflecting off of the large primary mirror sending it to the smaller secondary mirror. The secondary mirror reflects that light back through a hole in the primary mirror where it comes to a focus and enters each of the telescope’s many instruments located behind the primary mirror. Telescope diagrams are not to scale relative to one and another.
