The axicon lens is a specialized lens that bears a conical surface. The axicon lens images a point source as a line along the optic axis.
Autocorrelator is a tool used for measuring the autocorrelation of spectral components and optical beam intensity by investigating the variable difference is an optical path of the beam.
Fluorescent lamps are essentially cylindrical glass tubes that are coated with phosphorus and filled with a noble gas. They also contain a small amount of mercury inside. Conventionally, these lamps are shaped as hollow cylinders.
A neutral density filter is a semi-transparent glass filter used in front of a camera lens to reduce or vary the intensity of incoming light without affecting the color rendition.
The term photon was coined by Gilbert Lewis in 1926. A photon is a type of elementary particle that forms the basic unit of electromagnetic radiation, which includes infrared, ultraviolet, visible light, X-rays, radio waves, and gamma rays.
Wei Min, Assistant Professor at Columbia University and his team have investigated the synthesis of protein at a specific site in the tissue of the brain using a new imaging technique in order to study the process of development of long-term memory.

Wave optics, also referred to as physical optics, is the branch of optics that enables important phenomena such as interference, diffraction, and polarization to be understood.
Ultraviolet (UV) light is a portion of the electromagnetic spectrum between the visible rays and X-rays. It lies in the frequency range of 10 to 400 nm with photon energies from 3 to 124 eV.
Optical density is a term used in the field of optical spectroscopy for describing the propagation of a wave through a material.
Bandpass filter is a circuit or a device that allows transmission of signals at frequencies within a particular range and rejects signals at frequencies outside that range.
