Photomultiplier Tube
Introduction Photomultiplier tubes (PMTs) are a type of vacuum tube used to detect and amplify signals from individual photons. PMTs are known for their high sensitivity to light, fast response, and large amplification factors. Structure of a Photomultiplier Tube A PMT typically consists of three main components: Working Principle When a photon strikes the photocathode,…

Optics
Introduction Optics is a branch of physics that studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Nature of Light Light is an electromagnetic wave, and its speed in a vacuum…

Absorption, Photon
Photon absorption refers to the process by which an atom or molecule absorbs a photon and makes a transition to a higher energy level. This concept is at the heart of quantum physics and has a wide range of applications in various fields, including chemistry, biology, and materials science. (Please note that this process is intimately…
