Any form of laser; e.g., a dye laser, having an output that can be adjusted over a wide range of wavelengths. Normally the range is about 70 nm wide.
lineament
A mappable surface feature arranged in straight or curved lines that is distinguished from surrounding surfaces and is formed as a result of the landform's internal characteristics.

A device used to accelerate the electrons in a free-electron laser. There are several types, including the induction linear accelerator, the radio frequency linear accelerator and the superconducting...
linear actuator
High-precision motorized positioning device, often linked to computer control equipment.
linear amplifier
Amplifier in which the input and output pulse heights are directly proportional.
linear array
A solid-state video detector consisting of a single row of light-sensitive semiconductor devices, used in linear-array cameras.
linear element
A device for which the output electric field is linearly proportional to the input electric field, and no new wavelengths or modulation frequencies are generated.
linear encoder -> optical encoder
A device designed to measure linear or rotary motion by detection of the movement of markings on a transparent medium past a fixed point of light. The encoder has a moving code plate, a glass disc...
linear energy transfer
The transfer of energy lost by radiation to the body, relative to the loss of energy per unit of path traveled.
linear field
The measured width of the field of view at any distance.
linear image sensor
A linear image sensor is a type of solid-state electronic device used to capture and convert light into electrical signals. Unlike area image sensors (such as CCD or CMOS sensors), which capture an...
linear motion
Linear motion is the movement of an object or particle along a straight path in a single direction. It is one of the simplest forms of motion, described by parameters such as displacement, velocity,...
linear optics
Linear optics refers to the study and manipulation of light in a linear and deterministic manner, where the response of optical elements is proportional to the amplitude of the incident light wave....
linear plastic
A term for thermoplastic optical materials; that is, those in which the polymer chains remain linear after heating and molding and which thus can be remolded again and again, unlike thermoset...
linear polarization
Linear polarization refers to the polarization state of light where the electric field oscillates in a single plane as the light propagates through space. In other words, the electric field vector of...
linear positioning stage
A linear positioning stage, also known as a linear stage or translation stage, is a precision mechanical device used to accurately move and position objects along a linear axis. These stages are...
linear receive optics
Linear receive optics typically refers to the optical components and systems used in the reception (detection) of linearly polarized light signals in various applications, such as optical...
linearity
A relationship between two variables so that when plotted on a graph they yield a straight line.
lineation
Subsurface linear arrangement of elements of rock that is not mappable; lineation is a one-dimensional characteristic.
linewidth
Linewidth, also known as spectral linewidth or line width, refers to a measure of the width of a frequency spectrum of a signal or a resonance. It indicates the range of frequencies over which the...
link
In data communications, the instrumentation connecting two stations: transmitters, receivers and the cable that runs between them.
Linnik interference microscope
A Michelson-type interference microscope used to produce interference patterns of reflective specimens through the interference between light reflected by the specimen and that reflected by a...

lip
A defect in the cleaved end face of an optical fiber, in the form of a sharp protrusion at the edge of the fiber.
Lippich prism
A small half-shade analyzer placed in the eyepiece of a polarimeter to determine the character of the polarized light emitted by the instrument. It consists of a Nicol prism situated so that it...
liquid coating
A self-healing, index-matching, nonporous coating for optical components that can eliminate production difficulties and deficiencies associated with solid-film contamination and postdeposition...
liquid core optical fiber
Multimode straight fiber capable of transporting linearly polarized light with any incident polarization angle, and in which no form of internal stress can develop that could lead to birefringence.
liquid crystal
Liquid crystals are a state of matter that exhibits properties intermediate between those of conventional liquids and solid crystals. In a liquid crystal, the molecules are ordered like those in a...
