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.

NIST High-Power Calibration System Figure 1 shows a diagram of the previous NIST high-power laser detector calibration system in which a WTM was used as a beamsplitter to provide simultaneous beams to the device under test (DUT) and the primary standard calorimeter.
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).
