Magnifying glass
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.
Parts of Magnifying Glass
- Convex Lens
- Frame or Handle
- Lens Diameter
Working of Magnifying Glass
A magnifying glass utilizes the optical properties of a convex lens to refract and converge light rays, creating a magnified virtual image of small objects. This makes it easier for the human eye to observe and examine details that may otherwise be difficult to see with the naked eye. Magnifying glasses are commonly used to enlarge and clarify small text in books, newspapers, magazines, and documents, especially for individuals with vision impairments or presbyopia.
Optical Instruments
Optical instruments are devices designed to manipulate and detect light for various purposes, ranging from imaging to measurement and analysis. They utilize the principles of optics, which is the branch of physics that deals with the behavior and properties of light.
In this article, we will study about optical instruments, different types of optical instruments such as eye, lens, microscope, telescope, periscope, and kaleidoscope, and their working.
