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.

Similarly, a non-symmetric beamsplitter or polarizing optics can be used to combine the comb and test laser beams in proportions other than 50 %, which is slightly advantageous when the test laser has much less power than the comb (an iodine stabilized laser, for example).
Weisstein explains In its simplest form, a Fourier transform spectrometer consists of two mirrors located at a right angle to each other and oriented perpendicularly, with a beamsplitter placed at the vertex of the right angle and oriented at a 45[degree] angle relative to the two mirrors (Figure 1).
