WebA micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times.

WebJul 20, 2010 · The “F” number of a lens is the ratio of the lens focal length to the lens diameter. Therefore, if a lens has a 50mm focal length and a diameter of 10mm, the F number for that combination is 5. If a 50mm lens had an opening of 25mm, that combination would have an F number of 2. Lenses are normally listed as their maximum F number, in … WebA number of excellent books and review articles on phase contrast microscopy have been published by leading researchers in the field and were utilized as references to prepare the phase contrast discussions included in the Olympus Microscopy Resource Center Microscopy Primer. ... Photomicrography: A Comprehensive Treatise, Vol. II, Krieger ... In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture"). It is also known as the focal ratio, f-ratio, or f-stop, and is very important in photography. It is a dimensionless number that is a quantitative measure of lens … See more The f-number N is given by: where $${\displaystyle f}$$ is the focal length, and $${\displaystyle D}$$ is the diameter of the entrance pupil (effective aperture). It is customary to write f-numbers preceded … See more The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system that blocks certain rays. The aperture stop is the aperture setting that limits the brightness of the image by restricting the input … See more Computing the f-number of the human eye involves computing the physical aperture and focal length of the eye. The pupil can be as large as 6–7 mm wide open, which translates into the maximal physical aperture. The f-number of the … See more The system of f-numbers for specifying relative apertures evolved in the late nineteenth century, in competition with several other systems of aperture notation. See more Depth of field increases with f-number, as illustrated in the image here. This means that photographs taken with a low f-number (large aperture) will tend to have subjects at one … See more The camera equation, or G#, is the ratio of the radiance reaching the camera sensor to the irradiance on the focal plane of the camera lens: where τ is the … See more The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically … See more songs about the second coming
