Filament may refer to:
In physics and electrical engineering
- An electrical filament used to emit light in an Incandescent light bulb The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence . An electric current passes through a thin filament, heating it to a temperature that produces light. The enclosing glass bulb contains either a vacuum or an inert gas to prevent oxidation of the hot filament
- Current filament
- Filament propagation In nonlinear optics, filament propagation is propagation of a beam of light through a medium without diffraction. This is possible because the Kerr effect causes an index of refraction change in the medium, resulting in self-focusing of the beam, diffractionless propagation of a light beam
- Hot cathode In vacuum tubes, a hot cathode is a cathode electrode which emits electrons due to thermionic emission. In the accelerator community, these are referred to as thermionic cathodes. The heating element is usually an electrical filament. Hot cathodes typically achieve much higher power density than cold cathodes, emitting significantly more electrons, a filament in a vacuum tube that emits electrons
In astronomy
- Galaxy filament In physical cosmology, filaments are the largest known structures in the universe, thread-like structures with a typical length of 50 to 80 megaparsecs h-1 that form the boundaries between large voids in the universe. Filaments consist of gravitationally-bound galaxies; parts where a large number of galaxies are very close to each other are called
- Solar filament, equivalent to a solar prominence A prominence is a large, bright feature extending outward from the Sun's surface, often in a loop shape. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's corona. While the corona consists of extremely hot ionized gases, known as plasma, which do not emit much visible light, prominences contain
- Birkeland current A Birkeland current is a specific magnetic field aligned current in the Earth’s magnetosphere which flows from the magnetotail towards the Earth on the dawn side and in the other direction on the dusk side of the magnetosphere. Lately, the term Birkeland currents has been expanded by some authors to include magnetic field aligned currents in
In biology
- Protein filament In biology, a filament is a long chain of protein subunits, such as those found in hair, muscle, or in flagella. They are often bundled together for strength and rigidity. Some cellular examples include:
- Filamentation Filamentation is the anomalous growth of certain bacteria, such as E. coli, in which cells continue to elongate but do not divide . Bacterial filamentation is often observed as a result of bacteria responding to various stresses, including DNA damage or inhibition of replication. This may happen, for example, while responding to extensive DNA, a long chain of cells
- Part of a stamen The stamen is the male reproductive organ of a flower. Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The, the male part of a flower
- Hypha A hypha is a long, branching filamentous structure of a fungus, and also of unrelated Actinobacteria. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium; yeasts are unicellular fungi that do not grow as hyphae, in fungi A fungus is a member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. The Fungi (pronounced /ˈfʌndʒaɪ/ or /ˈfʌŋɡaɪ/) are classified as a kingdom that is separate from plants, animals and bacteria. One major difference is that fungal cells have cell and Actinobacteria Actinobacteria are a group of Gram-positive bacteria with high G+C ratio. They can be terrestrial or aquatic

- Filament, a Japan-based band.
In print
- Filament Magazine, a female-oriented erotica magazine.
Other uses
- Fiber Fiber, also spelled fibre, is a class of materials that are continuous filaments or are in discrete elongated pieces, similar to lengths of thread. They are very important in the biology of both plants and animals, for holding tissues together. Human uses for fibers are diverse. They can be spun into filaments, string or rope, used as a component or yarn Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery and ropemaking. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved
- Filament (textiles) Staple is a term referring to naturally formed clusters or locks of wool fibres throughout a fleece that are held together by cross fibres. The staple strength of wool is one of the major determining factors when spinning yarn as well as the sale price of greasy wool, clusters or locks of wool fibers
