A photoconductive cell is a two-way terminal semiconductor device where the terminal resistance varies linearly compared to the intensity of the incident light. Thus photoconductive cells are also known as photoresistive devices. There are two primary materials, cadmium sulfide as well as cadmium selenide. These are the two primary materials typically used to manufacture photoconductive […]

Introduction  A periscope is a device that allows an observer to look over, around, or through an object, impediment, or circumstance that limits direct line-of-sight observation from their current location. It comprises an exterior box with mirrors at either end arranged parallel to each other at a 45° angle in its most basic version. Periscope

Optics is the branch of physics that studies the behaviour of light and other waves. It includes the properties of waves, their propagation, and the methods used to measure them. Optics also includes the theory of lenses, mirror reflection, and images. Optical instruments use light to detect, measure, or image physical phenomena. They can be

Introduction  A number of optical instruments have been designed using the concept of reflection, refraction, lenses, prisms, and many more. Among these, microscopes and telescopes are two powerful instruments that have greatly aided our current understanding of the micro-and macrocosmic. In addition, the development of these gadgets resulted in breakthroughs in fields like physics, astronomy,

Introduction Multi-mode fibres usually have a wider core diameter and are used for short-distance communication links and for applications wherever high power should be transmitted. Single-mode fibres are used for communication links longer than 1,000 meters (3,300 ft.), having the ability to affix optical fibres with low loss or wastage is vital in fibre optic

Fiber optics is the technology that transmits information as pulses of light through strands of fiber optics or plastic over long distances. Optical fibers are about the diameter of a strand of human hair, and when combined into a fiber optic cable, they can carry more data over longer distances and faster than other media.

An optical instrument (sometimes known as an “optic” for short) is a device that processes light waves (or photons) in order to either enhance an image for viewing or analyze and detect the characteristics of the light waves (or photons). Periscopes, microscopes, telescopes, and cameras are examples of devices that fall into this category. An

The most familiar kind of magnifier is the optical, or light, microscope, within which glass lenses are wont to kind the image. Optical microscopes will be simple, consisting of one lens, or compound, consisting of many optical parts in line. The hand glass will enlarge concerning three to 20×. Single-lensed simple microscopes can magnify up

Introduction  An instrument that is used to extend the size of an object by magnifying it, is known as a microscope. It is basically used to see objects which are not visible from our naked eyes such as cells of plants and animals, nuclei, mitochondria, organelles, atoms, etc. A microscope is an instrument that is used to

When something is magnified, it is referred to as magnification. A larger apparent size is not the same as a larger physical size, as it refers to a dramatic increase in visual magnificence. The increase in visual magnificence can be quantified using a magnifying lens. Under magnification, it is important to consider how an object
