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?
By using a beam splitter in the collimated beam
, the laser beam andtheOCT measuring light are combined.
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.
Laser beam expanders are used within laser systems to expand or increase the size of a collimated beam
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.
