Optical Lens On A Telescope. It is responsible for gathering light from distant objects and forming an image. a telescope can also be made with a concave mirror as its first element or objective, since a concave mirror acts like a convex lens as seen in figure \(\pageindex{3}\). the objective lens is the most important part of a telescope’s optical system. a telescope using a lens for its main optical element is called a refracting telescope. the objective lens (in refractors) or primary mirror (in reflectors) collects lots of light from a distant object and brings that light, or image,. Like eyeglasses, the lenses bend, or refract, light passing through them. a second lens, referred to as the eyepiece lens, is placed behind the focal plane and enables the observer to view the enlarged, or magnified, image. the primary optical element in a telescope is either a convex lens (in a refracting telescope) or a concave mirror (in a reflector) that brings the light to a focus. the eyepiece, often called the ocular lens or telescope eye lens, plays a critical role in determining magnification, field of view and overall clarity of celestial observations. The eyepiece is a part of the telescope through which an observer looks. The size of the objective lens is called the aperture.
