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

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.

We are very excited about this new, higher extinction ratio because it escalates the level of proficiency to our beamsplitter thin film coating technology.
3) Flexibility and stability: The beamsplitter ratios of uncoated, WTM beamsplitters are determined by their indexes of refraction and are, consequently, fixed (and limited) for each laser wavelength used and type of material available.
This is an important feature of infrared spectrometers because it allows the instruments to perform a wider variety of measurements without the need for additional analysis or secondary equipment, such as additional beamsplitters or detector exchanges.
In power measurement systems, each beamsplitter is used either to sample part of the beam for a monitor detector or it is used as a calibrated standard itself.
The three arrays see the same region of sky simultaneously thanks to dichroic beamsplitters, which direct different wavelengths of infrared light to each.
