A reticle, or reticule [1] [2] also known as a graticule, is a pattern of fine lines or markings built into the eyepiece of an optical device such as a telescopic sight, spotting scope, theodolite, optical microscope or the screen of an oscilloscope, to provide measurement references during visual inspections.
A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.
Reticule can refer to: Reticle, fine lines in the eyepiece of a sighting device; Reticule (handbag), a type of small handbag This page was last edited on 29 ...
The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. [2] The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ).
Historically in photolithography for the mass production of integrated circuit devices, there was a distinction between the term photoreticle or simply reticle, and the term photomask. In the case of a photomask, there is a one-to-one correspondence between the mask pattern and the wafer pattern.
The preferred AE term is "reticle", sometimes "reticule", which is also occasionally found in BE. It is used by most authors to denote exactly the same thing as graticule, though the dictionary definition (Webster) is somewhat different: "Reticle — a system of lines, wires, or the like, in the focus of the eyepiece of an optical instrument."
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
Molecular physics is the study of the physical properties of molecules and molecular dynamics. The field overlaps significantly with physical chemistry, chemical physics, and quantum chemistry. It is often considered as a sub-field of atomic, molecular, and optical physics. Research groups studying molecular physics are typically designated as ...
