Source sentences:
text: Invented in the 1960s, it has a secondary mirror that bounces light through a hole in the primary mirror to an eyepiece.
text: Curved mirrors can bend the light and make parallel light rays converge to a focus, This focus is directly in the path of the incoming light,
text: The telescope had a flat diagonal secondary mirror bouncing the light at a 90° angle to a Plano-convex eyepiece with a probable focal length of 4.5mm yielding his observed 35 times magnification.
text: The mirrors bend light together by reflecting it rather than bending it as lenses do.
text: Like the Cassegrain reflector, a secondary mirror bounces light through a hole in the primary mirror to the eyepiece.
text: A secondary flat mirror is needed in order to bounce/bend the light at a 90 degree angle so that the focal point is now outside the main path of the primary mirror.
text: The light enters the tube and reflects off a curved mirror (called the primary mirror) at the other end, before bouncing back up the tube to near the top where it reflects off a smaller mirror (called the secondary mirror), which bounces the light out of a hole in the side of the telescope where you attach your eyepiece.
