beam

 [bēm]
a unidirectional, or approximately unidirectional, emission of electromagnetic radiation or particles.
useful beam in radiology, that part of the primary radiation that is permitted to emerge from the tubehead assembly of an x-ray machine, as limited by the aperture or port and accessory collimating devices.
beam splitter a device that reflects light from the output phosphor of an image intensifier to a photographic recording. Called also image distributor.

beam splitter

Radiation oncology
A device that divides a beam of electromagnetic radiation into 2 or more distinct beams.
 
Telemedicine
A device that divides the image beam of a clinical examining scope so the physician has the choice of looking at the image on a video monitor or directly through the scope.

beam splitter 

An optical system which separates an incident beam of light into two beams of lesser intensity, one reflected and the other transmitted, e.g. a semi-silvered mirror. Some beam splitters are made of birefringent material, which splits the incident light beam into oppositely polarized beams. They are called polarizing beam splitters. Example: Wollaston prism.

The latter means that measuring the number of photons at the horizontal output port does not depend on the result of detecting photons at the vertical output port of the beam splitter. This result enforces the notion of classicality associated with the conventional coherent states of light.
It was shown that the CNOT gate can be implemented using three partially polarizing beam splitters (PPBSs) with suitable polarization-dependent transmittance and reflectance, where the essential interaction is realized by a single intrinsic PPBS (PPBS A), while the other two supplemental PPBSs (PPBS B) act as local polarization compensators on the input qubits.
The included beam splitter made this model an attractive package for residency training programs.
With the use of the scan-tube lens, there is space to place a dichroic beam splitter in the sample arm.
The catch is that once the photon clears the beam splitter, the experimenter may place another beam splitter at a later point where the two paths intersect.
The beam splitters of the MZI were made by forming two coupling regions at two positions separated by a distance L in the fiber.

Broadband multispectral imaging for multilabeled specimens is supported by the dynamic beam splitter AOBS and has been further extended by expanding the SP prism spectrophotometer detection to five simultaneous channels.
Light enters the system, where it is divided by a beam splitter. Half the light is reflected by a fixed mirror, half by a moving mirror.
The cost is $1,200 without a beam splitter. If a beam splitter is needed, there is an additional $400 charge.
With the addition of another deflection head and a programmable beam splitter, a single laser can simultaneously mark two parts with the same information.
After focusing with a lens (f = 100 mm and d = 25 mm), and passing through a cube beam splitter and polarizer, a 0.9-mm-diameter beam normally incident on the sample surface was projected.
