What are the five optical instruments?
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.
Is the eye an optical instrument?
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. If the retinal images are too blurred, the visual system will not work properly.

Which optical instrument is used for medical purposes?
13.2. 3 Ophthalmoscope. An ophthalmoscope is an optical instrument for examining the interior of the eyeball and its back structures (called the fundus) through the pupil by injecting a light beam into the eye and looking at its back-reflection.
How mirror or lens is used?
Because mirrors reflect light, they create an illusion of open space by doubling whatever is in a room. Certain styles of mirrors may give a room a certain atmosphere based on their appearance. Additionally, decorators may use lenses to reflect light or add color.
What is a flat mirror called?
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.
What are the types of mirrors and lenses?
Basic lenses and mirrors come in two different kinds: concave and convex. These types differ in how and where they focus light. A concave lens diverges light—scatters it and cannot bring it into focus—and the ‘image’ that it forms shows up on the same side as the light it is reflecting.
