Neon lamps are gas discharge lamps that contain neon gas at a low pressure enveloped in a glass capsule. Gas discharge lamps emit light when electric light is passed through the gas.
A mercury vapour lamp is a high-pressure electric arc discharge lamp that provides intense illumination over a selected range of wavelengths.
Optical phase conjugation is a non-linear optical process, which is capable of time reversing the scattering process and healing the distortions in the wave front.
Resolution limits owing to light diffraction have always been a major problem in analysing microscopic images.
Spectrophotometers, like all spectrometers, are devices used to discover the components which make up a material.

The technical field of microscopy deals with the use of different types of microscopes to view and study samples and objects that otherwise cannot be viewed with the naked eye.
Confocal microscopy is a versatile imaging method, through which viewing cells and tissues is made possible. It is a major improvement from conventional light microscopy, as it also helps create images in 3D.
Light sheet fluorescence microscopy (LSFM), also known as selective plane illumination microscopy (SPIM), is a non-destructive, versatile imaging tool, which operates as a microscope and microtome, using a plane of light to optically section and view tissues and living organisms with remarkable sub-cellular resolution.
Arc lamps are a category of lamps that produce light by an electric arc (also known as a voltaic arc). The lamp consists of two electrodes that are separated by a gas.
Argon lamps are gas discharge lamps that contain argon gas at a low pressure enveloped in a glass capsule. Gas discharge lamps emit light when electric light is passed through the gas. Argon lamps emit a distinct blue glow.
