An object glass; called also objective lens. See under Object, n.
The optical element which receives light from the object and forms the first or primary image in telescopes, microscopes and other optical systems.
The main mirror or lens of a telescope that collects and focuses light.
A lens or system of lenses that forms an image of an object.
Term referring to the main mirror or lens of a telescope.
The principal lens or mirror of an optical system.
The lens used closest to the specimen in microscopes or telescopes.
The primary mirror of a reflecting telescope or the primary lens of a refractor.
This is the thing that gathers light from the sky and folds the light into a cone. In a refractor it is the big lens that points at the sky, in a reflector it is the big mirror at the bottom of the tube. The job of the objective is to create a light cone which comes into tight focus at a single focal point.
Main lens or mirror of the telescope.
the primary optical element of a telescope, it gathers the electromagnetic radiation and does the initial focussing.
The lens which is closest to the object being observed.
the lens or system of lenses nearest the object being viewed
That which is based, as near as possible, on physical actuality or optical perception. Such art tends to appear natural or real
The main light gathering optic in a telescope or binocular.
The term objective is used to refer to the lens of a refracting telescope. The objective lens of a refractor is simply the main lens at the front of the telescope.
In a microscope, the objective (also called the objective lens) is the lens nearest to the object being examined whereas the lens closest to the eye is termed the ocular (the eyepiece). See the entire definition of Objective
a telescopeâ€(tm)s primary lens or mirror that gathers light and brings it to a focus
The very first optical element at the front of a lens.
The optical lens in riflescopes that receives light and forms the primary image. The image is magnified by the Ocular.
The lens or combination of lenses which receives light rays from an object and refracts them to form an image in the focal plane of the eyepiece of an optical instrument, such as a telescope. Also called object glass.
of a microscope, the primary magnifying system, consisting of a system (generally of lenses, less frequently of mirrors) forming a real, inverted, and magnified image of the object viewed. Also see eyepiece.
The primary or largest optics piece in a telescope."
The objective is the light-gathering lens (or mirror) of a telescope.
An objective (or object lens, object glass, objective lens or photographic objective) is an optical system or device containing a combination of lenses that receive light rays from an object and form an image on the focal plane. A photographic lens is an objective.
the optical system of the microscope near the specimen. The objective projects the specimen image into the intermediate image plane of the microscope tube.
a telescope's main light-gathering lens or mirror.
The light collecting part of a telescope i.e. the main mirror or the lens at the front of a refracting telescope.
An objective in optics is the lens or mirror in a microscope, telescope, camera or other optical instrument, that receives the first light rays from the object being observed. The objective is also called the object lens, object glass, and objective glass.
