beam splitter

   Also found in: Dictionary/thesaurus, Acronyms, Encyclopedia, Wikipedia 0.03 sec.
beam splitter,
a device that reflects light from the output phosphor of an image intensifier to a photographic recording. Also called image distributor.
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 
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.

Key elements of the optical system include the beam path design with its maximum optical precision and the uncompromising concentration on the essentials, the beam combiner system for extremely accurate beam coupling and superimposition, the beam splitter with continuous and loss-free splitting of the light spectrum and, last but not least, the extremely stable pinhole.
