This document discusses and defines different types of optical instruments. It provides examples and descriptions of cameras, microscopes, telescopes, compound microscopes, endoscopes, binoculars, spectrometers, overhead projectors, and magnifying glasses. These instruments process or analyze light in some way, such as to enhance images for viewing, examine small objects, observe distant objects, or determine the properties of light. Common uses include photography, microscopy, astronomy, medical procedures, and classroom demonstrations.

An 

optical instrument (or "optic" for


short) is a device that processes light
waves (or photons), either to enhance
an image for viewing or to analyze and
determine their characteristic properties.
Common examples include
Camera
Endoscope
Spectrometer
Binocular
Compound,microsope
Overhead projector
Magnifyingglass
Microscopes 
Telescopes
A camera is an optical instrument that
captures a visual image. At a basic level,
cameras are sealed boxes (the camera body)
with a small hole (the aperture) that
allows light through to capture an imageon a
light-sensitive surface (usually photographic
film or a digital sensor). Cameras have
various mechanisms to control how the light
falls onto the light-sensitive surface. 

A microscope  is a laboratory


instrument used to examine objects that are
too small to be seen by the naked
eye. Microscopy is the science of
investigating small objects and structures
using a microscope. Microscopic means
being invisible to the eye unless aided by a
microscope.
A telescope is an optical instrument using
lenses, curved mirrors, or a combination of
both to observe distant objects, or various
devices used to observe distant objects by
their emission, absorption, or reflection of
electromagnetic radiation.[1] The first known
practical telescopes were refracting
telescopes with glass lenses and were
invented in the Netherlands at the beginning
of the 17th century.

A compound microscope is an instrument


that is used to view magnified images of
small specimens on a glass slide. It can
achieve higher levels of magnification than
stereo or other low power microscopes and
reduce chromatic aberration. It achieves this
through the use of two or more lenses in the
objective and the eyepiece.
Endoscop a lighted optical instrument that
is used to get ea deep look inside the body.
An endoscope, which may be rigid or
flexible, can be used to examine organs, such
as the throat or esophagus. Specialized
endoscopes are named for where they are
intended to look.

binoculars, optical instrument, usually


handheld, for providing a magnified
stereoscopic view of distant objects. It
consists of two similar telescopes, one for
each eye, mounted on a single frame. ...
Binoculars are designed to give an upright
view that is correctly oriented left-to-right.
A Spectrometer is any instrument used to
probe a property of light as a function of
its portion of the electromagnetic
spectrum, typically its wavelength,
frequency, or energy Technically, a
spectrometer can function over any range of
light, but most operate in a particular region
of the electromagnetic spectrum.

An overhead projector, like a film or slide


projector, uses light to project an enlarged
image on a screen, allowing the view of a
small document or picture to be shared with a
large audience
A magnifying glass is a convex lens that is
used to produce a magnified image of an
object. The lens is usually mounted in a
frame with a handle. A magnifying glass can
be used to focus light, such as to concentrate
the sun's radiation to create a hot spot at
the focus for fire starting
