For an optical system, which may consist of multiple lenses and other optical elements, the above definition of the focal length cannot be used, as it is not clear a priori for an extended system where to measure the distance to the focus: from the entrance into the optical system, from ...
The lens is at a distance of twice its focal length from both the screen and the spherical surface. A relation between the aperture of the lens, its focal length, the diameter of the bright spot and the radius of curvature of the spherical mirror is derived. The method is simple and ...

Nagy and Buchler [8] reported the results of radioscapholunate arthrodesis in 17 patients, but they underscored the poorer results in patients who had undergone multiple operations before the arthrodesis procedure. They emphasized the good tolerance of mediocarpal osteoarthritis and the relation of ...

a surface containing a pinhole is mounted on a micromanipulator and placed in front of a photodetector. A lens of known focal length is positioned along the laser beam for focusing the beam on the photodetector. The radius of the Gaussian beam is then measured by scanning the beam with the ...
