Source sentences:
text: Their designs can have simple all-spherical surfaces and can take advantage of a folded optical path that reduces the mass of the telescope, making them easier to manufacture.
text: These designs take advantage of all the surfaces being "spherically symmetrical" and were originally invented as modifications of mirror based optical systems (reflecting telescopes) to allow them to have an image plane relatively free of coma or astigmatism so they could be used as astrographic cameras.
text: That allows the design to take advantage of the many good qualities of low power lenses.
