Source sentences:
text: Because the light is passing through the lens, the surface of the lens has to be extremely smooth.
text: This occurs because as light passes through a lens, different colors are bent through different angles (like in a prism) and brought to a focus at different points.
text: In a refractor telescope, light passes through the lens at the front and travels directly to a mirror at the back of the scope and then into the eyepiece.
text: Towards the end of the telescope tube, at least one or more lens tend to draw in the light which then passes through the lens and down the length of the telescope tube, where the incident light is bent.
text: A refracting telescope uses a lens and as light passes through the lens it is focused down to a pinpoint.
text: Light which passes through the lens is bent, so that initially parallel rays meet near the bottom of the tube.
text: As light passes through the lens, some of it is absorbed by the glass; this is a relatively minor problem for visible radiation, but can be severe for infrared and ultraviolet observations because glass blocks most of the radiation in those regions of the electromagnetic spectrum; does not affect mirrors
