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

a device that reflects light from the output phosphor of an image intensifier to a photographic recording. Also called 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 Utah engineers have developed an ultracompact beamsplitter -- the smallest on record -- for dividing light waves into two separate channels of information.
In a simple theoretical formulation let us consider an open-air OCT system with a beamsplitter, reference and sample paths and a Gaussian-shape broadband source.
To compare those spectra with the spectroscopic features of the silane coupling agent itself, the attenuated total reflection (ATR) mode with a KBr beamsplitter and a DTGS detector was used.
Shorter beam paths were used, in order to be adapted for the higher-diverged laser beam; thus, making it very difficult to block the unused, higher order beams coming from the beamsplitter.

This beam is sent through a beamsplitter which transmits most of it, adjustable to be at the TSI irradiance level, to the TSI radiometer.
All spectra were recorded on a rapid scanning Fourier Transform Spectrometer (BioRad FTS-175C) scanning at 1 scan/sec, with an extended range KBr beamsplitter and Peltier-cooled DTGS detector, and with a full spectral range of 8300-470 [cm.
