“A photon is a fundamental particle that acts as a quantum of the electromagnetic field.”

“In scintillation counting, a fluorescent material absorbs the energy of the photon and emits a new photon as a flash of light in response.”

“The ferrioxalate actinometer is a photon counter and is sensitive to wavelengths less than 450 nm.”

“Spie recognizes optics and photonics as an important technological branch of modern physics.”

“Our three-year high school photonics program encourages students to train as laser technicians, and holography teaches them many useful skills.”

“The company is truly high-tech, making complex laser machines that cut silicon and wafers for chipmakers and photonics companies.”

“By comparison, on a sunny day the human eye is flooded by about 10 quadrillion photons per second.”

“Researchers have previously demonstrated that single atoms can be used to temporarily store photons in a quantum state.”

“In a confocal microscope, light passes through a pinhole to eliminate photons from outside the image plane.”
