What instrument uses lens?

A light microscope is an instrument that uses lenses to make enlarged images of objects that are too small for the unaided eye to see.

What are the 3 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.

Which is an optical instrument?

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 lens an 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 four optical instruments?

I. All of these instruments contain the same five basic components (source, sample holder, wavelength selector, detector, and signal processor) but differ in the configuration of these components.

What is the most important optical instrument?

A camera is an optical instrument that makes use of a convex lens. Hence, option A is the right answer. Note: It is to be noted that though a convex lens is used as a camera lens, the concave lens is also of great importance and hence used in the camera.

What are 5 optical devices?

Magnifying glasses or loupes are used for quick inspection with a low magnification; binocular microscopes are used to observe from 10x to 50x, and upright/inverted microscopes are used to observe from 50x to 1500x.

What are the components of optical instruments?

An object is anything that is being viewed, e.g., when one looks at a tree through a lens, with a mirror or any other optical device the tree is referred to an optical object.

Is camera an optical instrument?

Uses of a Convex Lens Convex lenses are used in microscopes, magnifying glasses and eyeglasses. They are also used in the cameras to create real images of objects present at a distance. The nature of the images depends on the way these lenses are used.

How do you make an optical instrument?

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.
