cadmium lamp
A mercury vapor discharge lamp that has cadmium added to emit radiation in the red region as a complement to the mercury vapor's blue and green radiation.
cadmium lines
The three lines in the spectrum of cadmium that have the purest radiations and that were first used by Michelson to calculate the standard meter.
cadmium red line
The narrowest line of the cadmium spectrum; the red line has the purest radiation.
cadmium sulfide
An inorganic compound, yellow to orange in color, that fluoresces strongly enough when bombarded by a high-current-density electron beam to be used as a high-intensity light source.
cadmium sulfide cell
A photoconductive cell having cadmium sulfide as its photoconducting material for the production of a very high dark-light resistance ratio.
cascade amplification
In a series of amplifiers, amplification by each of the preceding output.
cascade image tube
An image tube that functions in low-light-level conditions by virtue of its series of stacked sections wherein the output of one section becomes the input for the next.
cascade method
A heterochromatic photometric process using successive comparison of similar chromaticities and the calculation of relative luminances of unlike chromaticities as the product of ratios of luminances...
cascade shower
A shower of cosmic rays whereby a high-energy electron produces one or more photons that convert into electron pairs, the secondary electrons producing the same effects as the primary. As the process...
cascade tube
An instrument consisting of a high-voltage vacuum tube used to form hard x-rays or high-speed ion beams. By partitioning the tube into separate sections, the total voltage is divided.
cathode-coupled amplifier
A cascade amplifier that uses a common cathode resistor to couple energy from stage to stage.
cell adhesion
Cell adhesion refers to the process by which cells interact and attach to neighboring cells or to the extracellular matrix (ECM), a network of proteins and other molecules surrounding cells. This...
channel electron multiplier
A photoelectric detector consisting of a glass tube internally coated with a low conductance material. Voltage applied along the tube causes photoemission from the photocathode at the end of the tube...
coagulation
Coagulation refers to the process of transforming a liquid, particularly blood or a solution containing dispersed particles, into a solid or semi-solid state. This term is most commonly associated...
computer numerically controlled grinding
Computer numerically controlled (CNC) grinding is a manufacturing process that utilizes computerized controls and precision machining tools to remove material from a workpiece. In CNC grinding, a...

channel electron multiplier
A photoelectric detector consisting of a glass tube internally coated with a low conductance material. Voltage applied along the tube causes photoemission from the photocathode at the end of the tube...
cryogenically cooled LWIR camera
A cryogenically cooled long-wave infrared (LWIR) camera is a specialized thermal imaging device designed to detect infrared radiation in the long-wave infrared spectrum, typically ranging from 8 to...
custom optic
A custom optic refers to an optical component that is designed, manufactured, and tailored to meet specific requirements or applications. These optics can include lenses, mirrors, prisms, filters, or...
