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.
