What are the two 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.

How many types of optical instruments are there?

Types of Optical instruments. The instrument that forms enlarged images, of very tiny objects that are not visible to the human eye, by using lenses is known as a light microscope. There are four types of microscopes; these are: Compound microscope.

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 optical measuring instruments?

An optical CMM, similar to optical comparators and measuring microscopes, is a non-contact instrument that uses images to perform measurements. Optical CMMs are also known as CNC image measuring machines, where “CNC” is an abbreviation of Computer Numerical Control.

What is meant by optical instruments?

Optical instruments are the devices which process light wave to enhance an image for a more clear view. The use of optical instruments, such as a magnifying lens or any complicated device like a microscope or telescope, usually makes things bigger and helps us to see in a more detailed manner.

Is Periscope a optical instrument?

A periscope is an optical instrument that uses a system of prisms, lenses or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube.

Is magnifying glass an optical instrument?

Magnifying glasses are a simple optical devices used for viewing details of objects with some magnification. They are sometimes regarded as being the same as loupes, but precisely speaking a loupe is used in a close distance from the eye, while magnifying glasses (or hand lenses) are held at a larger distance.

Is Prism an optical instrument?

prism, in optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light. An ordinary triangular prism can separate white light into its constituent colours, called a spectrum.

Is mirror an optical device?

A mirror is an optical device which can reflect light. Usually, however, only those devices are meant where the angle of reflection equals the angle of incidence (see Figure 1). This means that diffraction gratings, for example, are not considered as mirrors, although they can also reflect light.

Which optical instrument forms a real image?

This is the mechanism used by telescopes, binoculars and light microscopes. The objective lens gathers the light from the object and projects a real image within the structure of the optical instrument. A second lens or system of lenses, the eyepiece, then projects a second real image onto the retina of the eye.
