Furthermore, because the light is refracted or bent, the image generated is not always clear. This also influences the physical size of the telescope, so they can end up being very large. Firstly, the power of the convex lens is governed by the size of the convex lens. Unfortunately, two main problems are associated with the refracting telescope. This focus point is where the image is created. This design allows the light to be bent into a single point of focus. Convex lenses are designed specifically to be thicker at the center and thinner at the edges. This convex glass lens is commonly referred to as the objective lens. Refractor or refracting telescopes use a convex glass lens to refract or bend light, bringing it into focus.

The eyepiece lens captures the bright, focused light from the objective lens, and magnifies it or spreads it out over the retina of the observer’s eye. The magnification of a telescope is performed by the eyepiece lens and depends on the combination of lenses used. In general, a larger aperture will result in a brighter image, as more light has been ‘collected’.īetween the objective lens/primary mirror and the eyepiece lens, the light is focused because the lenses are curved. The main purpose of the aperture is to allow light to enter the telescope. This is also commonly referred to as the aperture. The ability for a telescope to collect light is related to the objective lens’ diameter. To make this possible, an optical telescope uses the following two instruments: Image Credit: Lia Koltyrina/Īn optical telescope is an instrument that can make distant objects appear much closer.
