What are the optical instruments and their uses?
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 periscopes, microscopes, telescopes, and cameras.

What is the most important optical instrument?
The Eye. The most important optical instrument! Works differently from any other optical instrument (such as camera, telescope..) in that focussing is performed by deforming the lens by the eye muscles.
What are three optical devices?
Three optical instruments are cameras, microscopes and telescopes.
What are the three optical instruments?
What is the principle of optical instrument?
The basic principle for this is the transmission of bundled electromagnetic waves and the reception of emerging echoes due to reflection on objects and surfaces. Whereas radar systems work with invisible short-wave radio waves, optical instruments send visible electromagnetic impulses (laser).
What are the optical instrument of the eye?
The eye, the first element in the system, is a simple optical instrument. It is composed of only two positive lenses, the cornea and the crystalline lens, that project images into the retina to initiate the visual process.
What are the optical instruments used in a microscope?
A microscope is an optical instrument used to view small objects by enlarging them with two convex lenses. Optical microscopes, used for research, illuminate samples with visible or ultraviolet light….Viewable objects by magnification.

What is the function of optical instruments?
Optical instruments are based on optics. They use mirrors and lenses to reﬂect and refract light and form images. • The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object.
What are the different types of optical instruments?
Optical Instruments Example 1 Eyes. If we look at the structure of eyes when light falls on the eyes, the iris controls how much light enters the eye, it expands when it’s dark all 2 Lenses. On average, the near vision of an eye is 25 cm. 3 Magnifying Glass. 4 Astronomical Telescope. 5 Microscope. 6 Periscope.
How is light used in optical devices?
The use of light in devices such as these is possible because of optics. Optics and Optical Instruments Optics is the study of visible light and the ways it can be used to extend human vision and do other tasks.
What is the most important optical instrument in human body?
It is a most important organ of the human body which enables us to view all things around us. An eye is one of the most important optical instrument. Let us study in detail about other optical instruments used by us.
