collimated beam

collimated beam

[′käl·ə‚mād·əd ′bēm]
(physics)
A beam of radiation or matter whose rays or particles are nearly parallel so that the beam does not converge or diverge appreciably.

collimated

In a straight line. Collimated light beams are parallel rays of light.

For example, the ShadowMike sensor uses a green LED laser diode array source that provides a uniform collimated beam that lasts longer than traditional LED light and provides high-intensity, evenly distributed lighting.
The Gemini has: very high throughput, because it provides 10mm clear aperture (free space propagation with a collimated beam through the device, lacking entrance or exit slits); user adjustable spectral resolution without affecting light throughput; an ultra?
A collimator is a lens or lens mechanism that is placed in front of an optical fiber to produce a collimated beam. In combination with the rest of the arm, it forms an imaging system that images the fiber tip on the sample and, conversely, it images the focal plane of the objective on the tip of the optical fiber.
The binoculars act as a complete optical system, using the entire front aperture to gather light and focusing it into a collimated beam that comes out the eyepieces.
A green SLM laser was used to create a one inch diameter collimated beam at normal incidence to a holographic plate.
PearlBeam, from AquiSense Technologies, is a compact Collimated Beam Device, which employs UV- LEDs and emits radiation in the germicidal range.
Laser beam expanders are used within laser systems to expand or increase the size of a collimated beam.
More recently, a rectangular collimator device has been marketed with enhancement features that may help minimize the collimator cut technique errors created with a rectangular collimated beam. A device composed of a magnetic alignment ring and a positioning-indicator laser beam with a visual light and audible signal was designed to eliminate collimator cuts and retakes.
Consider a collimated beam of monoenergetic electrons that is directed at an opaque wall containing two narrow, parallel, and closely spaced slits A and B, with a detection screen at some distance beyond the slits.
