| Abbe limit | <physics> Ernst Abbe's specification for the limit of resolution of a diffraction-limited micro-scope. According to Abbe, a detail with a particular spacing in the specimen is resolved when the numerical aperture of the objective lens is large enough to capture the first-order diffraction pattern produced by the detail at the wavelength employed. See: Rayleigh criterion, Sparrow limit. (05 Aug 1998) |

| Abbe apertometre | <optics> In microscopy, a device for measuring simultaneously, the numerical and angular apertures of an objective or condenser. The back focal plane of the objective is viewed within auxiliary lens, and the device is set to show the position of an indicator just cutting into two opposite edges of the conoscopic field of view.

| Abbe, Ernst | <person> German mathematician and physicist, professor at Jena, and inventor of much optical apparatus at the Zeiss works. His inventions include the apochromatic objective, the compensating ocular, the Abbe condenser, a well corrected oil-immersion achromatic condenser, the immersion objective, Abbe apertometre, Abbe refractometre, and the drawing camera, he evolved the Abbe theory of resolution and microscope imagery, the numerical aperture formula, and other optical theories. Lived: 1840-1905. (05 Aug 1998) |

| Abbe's condenser | A system of two or three wide-angle, achromatic, convex and planoconvex lenses that may be moved upward or downward beneath the stage of a microscope, thereby regulating the concentration of light (directly from a bulb or reflected from a mirror) that passes through the material to be examined on the stage. (05 Mar 2000) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser. (05 Aug 1998) |
| Abbe substage apparatus | <apparatus> Includes a rack and pinion for horizontal displacement of an iris diaphragm to obtain oblique lighting. (05 Aug 1998) |
| Abbe test plate | <equipment> A long, wedge-shaped coverslip about 0.20 mm thick at one end and 0.10 to 0.12 mm at the other end coated chemically with a silver film on which are ruled horizontal lines. at each variation in thickness of 0.01 mm there are vertical lines. By means of oblique illumination and by focusing on different portions of the plate, it is possible to determine the optimum coverslip thickness for any objective and also, for microscopes with drawtubes, the tube length for best objective performance. The approximate freedom from spherical and chromatic aberrations can also be estimated. Small isolated bits of silver near the edges of the lines form good objects for the star test (05 Aug 1998) |
| Abbe theory of image formation | <optics, physics> Abbe's theory is based on the fact that a non-self-luminous particle, which is illuminated by an extraneous source, gives rise to diffracted light rays, in addition to the dioptric pencil. He stated that to form a good microscopical image as many of the diffracted rays as possible should be intercepted by the objective. With closely ruled lines, his theory is easily demonstrated by observing the back lens of the objective, for here the diffracted rays can be observed directly if the aperture diaphragm is closed. It can be shown that, when the illumination is arranged to exclude the diffracted images, resolution is lost. (11 Mar 1998) |
| condenser, Abbe | <microscopy> Originally a two-lens substage condenser combination designed by Ernst Abbe. It lacks chromatic correction though designed for a minimum of spherical aberration and has only a very low-angle aplanatic cone. It may be rated with a numerical aperture as high as 1.3.

| beta limit | <radiobiology> if the plasma pressure in a tokamak becomes too high, the so-called ballooning modes become unstable and lead to a loss of confinement (sometimes catastrophic, sometimes not). The exact value at which this occurs depends strongly on the magnetic field B, the plasma minor radius a, and the toroidal plasma current I, such that maximum value of the normalised beta, beta_N=betaBa/I, is around 4% (with B in Teslas, a in metres, and I in Mega-amperes). The exact value depends on details of the plasma shape, the plasma profiles, and the safety factor. Synonym: troyon limit. (09 Oct 1997) |
| visibility, limit of | <microscopy> For the normal eye, the limit of visibility is considerably below the limits of resolution. It depends largely on contrast and intensity of illumination. (05 Aug 1998) |
