A telescope which uses lenses to gather and focus light.
A telescope that uses lenses to bring light to a focus.
A telescope that uses a clear (glass) objective to refract, or bend, the light to form an image at the focal plane. Binoculars are really just two small refracting telescopes. Small astronomical refractors are common, but larger ones (4"+) can get very expensive.
A telescope that has a large lens that collects and focuses the light from the object being observed.
Telescope that uses lenses to collect and focus light.
A telescope that uses a lens to focus light by bending it.
A telescope which uses a lens to gather and focus light from a distant object.
optical telescope that has a large convex lens that produces an image that is viewed through the eyepiece
an instrument that is constituted of one or several lenses and that focuses the luminous rays toward one point called focus
a type of telescope that focuses light with a lens
A telescope in which the principal optical component (objective) is a lens or system of lenses.
An optical system where light is bent through clear lenses.
A refracting telescope uses two lenses which magnify what is viewed; the large primary lens does most of the magnification. The first refracting telescope was invented by Hans Lippershey in 1608.
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image.
