An optical instrument 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 .
Learn what optical instruments are and how they use light waves to enhance images. Find out the types of optical instruments, such as microscope, telescope and magnifying lens, and their applications and ray diagrams.
- Converging lenses are used to make things appear larger.
- Diverging lenses are used to make things appear smaller.
- Optical instruments are devices that process light waves to enhance an image for a more clear view.

- A microscope features two converging lenses.
An optical instrument either processes light waves to enhance an image for viewing, or analyzes light waves (or photons) to determine one of a number of characteristic properties. The intent of the …
Jun 11, 2024 · Optics is the branch of science that deals with the nature, properties, and applications of light and optical systems. Learn about the history, principles, and types of optical instruments, such as lenses, mirrors, and prisms, and how they produce images and information.
6 days ago · Learn about the definition, examples, types and functions of optical instruments that reflect and refract light to form images. Explore the structure and working of eyes, lenses, microscopes, telescopes, periscopes, cameras, lasers and optical fibres.
- The magnifying power is determined by how much angle an object subtends. So, if an unaided eye subtends an angle of 2, and if the object subtends s...
- The magnifying power of a telescope can be calculated by using the following formula:M = (angle between the centre of the objective lens and the he...
- The advantages of a light microscope are as follows:Easy to use, small, and lightweight.High observational quality, and remains unaffected by elect...
- The types of lenses are:Normal lensesZoom lensesTelephoto lenses
- The human eye continues to see the image for some time when the image of the object is formed at the retina of the eye even when the object is remo...
- The most primary difference between a telescope and a microscope is that the telescope is used to see extremely large objects which are at a far-aw...
- The lenses which are thicker around their edges than at their centres are known as concave lenses while the ones thicker at their centres are known...
- An eye condition when objects at a distance start to appear blurred while the objects which are closer are seen clearly is known as short-sightedne...
- Convex lens and concave mirror can both have a positive focal length and form images with similar characteristics and both of them can converge par...
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. [1] . Optics usually describes the behaviour of visible, ultraviolet, and infrared light.
Learn how the eye, microscopes, and telescopes work based on the principles of optics and imaging. Explore the physics of vision correction, color, and aberrations with examples and applications.
