A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses.
The refracting telescope is a closed tube with an object glass, or objective lens, at one end and an eyepiece lens at the other end. The objective lens refracts, or bends, the light rays to a focal point near the other end of the tube.
There are two basic types of light telescopes: refracting telescopes and reflecting telescopes. A refracting telescope uses lenses. A lens is a curved piece of glass that refracts, or bends, light. A reflecting telescope uses mirrors.
11 Οκτ 2024 · A telescope made with lenses is called a refracting telescope. A lens, just like in eyeglasses, bends light passing through it. In eyeglasses, this makes things less blurry. In a telescope, it makes faraway things seem closer.
Reflecting Telescopes. Reflecting telescopes use mirrors instead of lenses to focus the light. A concave mirror is used to gather light and reflect it back to a focal point. In order to get the light out of the telescope, another mirror is used to direct the light to an eyepiece.
12 Μαΐ 2020 · A refracting telescope, or a refractor, uses a combination of lenses to produce images of distant objects, e.g., stars and planets that would otherwise not be visible with the human eye. A simple refracting telescope is made up of two lenses, which are called the objective and the eyepiece.
