A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
The type of telescope that uses convex lenses to increase the size of the image viewed is a refracting telescope. In this telescope, light enters through a lens at the front (objective lens) that converges the light to form an image, which is then magnified by a second lens (eyepiece lens) for viewing. Refracting telescopes are commonly used in terrestrial and astronomical observations due to their simplicity and effectiveness in magnifying distant objects.
A refracting telescope uses two lenses - an objective lens to gather light and focus it and an eyepiece lens to magnify the image.
Yes, the Hubble Space Telescope was launched with a flawed primary mirror rather than a missing lens. The mirror had a manufacturing error that affected its shape, leading to blurred images initially. This was rectified through a repair mission in 1993, successfully improving the telescope's performance.
Sir Isaac Newton is credited with inventing the first practical reflecting telescope, which used a concave mirror as the primary optical element instead of a lens. This design helped to minimize chromatic aberration, a common issue associated with traditional refracting telescopes that used lenses.
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.

Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
One major problem with the refractor telescope used by Galileo was sagging lens.
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.

A Barlow lens is an accessory used in telescopes to increase the focal length, resulting in magnification of the image. It allows the telescope to achieve higher magnification without needing to switch to a higher power eyepiece. By inserting the Barlow lens between the telescope and eyepiece, it effectively doubles or triples the focal length of the telescope.
The two lenses on a refracting telescope are typically called the objective lens (at the front of the telescope) and the eyepiece lens (at the back of the telescope). The objective lens gathers and focuses light from distant objects, while the eyepiece lens magnifies the focused image for the viewer.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
The "objective" lens (as opposed to the eyepiece).
In a reflector telescope, the primary mirror reflects and focuses light to the eyepiece. There are no lenses in the optical path of a reflector telescope.
