gravitational lensing: stronggalaxies: clusters: generalThe accuracy of mass estimates by gravitational lensing using the thin-lens approximation applied to NavarroFrenkWhite mass models with a soft truncation mechanism recently proposed by Baltz, Marshall and Oguri is studied. The gravitational lens ...
The thin lens equation is an equation that locates the image of a given object formed when it is placed in front of a lens. The "thin" part of a thin lens is an approximation that ignores almost all of the lens' properties ...
Thin Lens Equation Calculator is a physics/math tool designed to quickly and easily find object distance, image distance, focal length, and magnification. Feat…

Equation 1 is only strictly valid for monochromatic waves. When working with short laser pulses, there will be a temporal walk-off between the SH pulse generated at the front and back surface of the sample which Eq. 1 does not account for. The pulse at the fundamental wavelength will ...
For some experiments, images were collected on a Biorad 1024 confocal microscope with a 63× plan-apochromat lens (NA 1.40) (Zeiss). The pixel size was set to 0.100 μm using the zoom function. The pinhole was opened maximally to collect the most light and approximate wide field images Z...
The highest angle of incidence is dependent on the focusing power or numerical aperture of the lens. The maximum angle &thetav m is given by the following equation: (1)&numsp &numsp &numsp Sine &thetav m = (numerical aperture) The location of any ray in the reflected probe beam ...
This is just an approximation since the quantum defects vary with n and are expected to be temperature-dependent as well. Typical methods to extract the quantum defect as a function of n, such as those used in36, require the observation of high energy peaks whose quantum defects approach a ...
Thus, studies of crumpled systems might offer a new lens through which to interpret other complex processes. An immediate extension of this work would be a validation of the results on sheets of varied thicknesses and material parameters, as well as those prepared according to different compaction...
The intensity of the characteristic X-ray depends, in a first approximation, linearly on the concentration of the element of interest, i.e. matrix effects can be neglected. Simplifying eq. 2 into eq. 4 is possible when the total mass per unit area satisfies: [Math Processing Error]mthin<...
