- W2018242798 abstract "AbstractFor optical systems with smaller field angle the correction of spherical aberration isadvanced. For such systems the use of aspherics allows either improvement of imagequality or reduction of the number of lens elements required to achieve the aforegivenimage quality. Optical systems in the visible spectral region used for technicalapplications like optical data processing can be attached to this type. Here the use ofaspherics is advantageous. By reducing the number of elements veiling glare can also beminimized. When observing systems in the infrared spectral region with not too large afield angle, the use of aspherics makes the corrections easier. This is important becausein the infrared region only a few optical transparent materials are available. Thepossibility to reduce the number of elements allows the reduction of weight of the wholesystem. Typical aspherics for such systems in the visible and the infrared spectralregion are shown and their advantages demonstrated. The required accuracy of theseaspherics is specified.IntroductionIt is the purpose of any lens design to transfer spherical wavefronts entering on theobject side into spherical wavefronts emerging on the image side. If this requirement ismet with sufficient accuracy, the images of luminous object points will be limited onlyby diffraction. Even for monochromatic light, a single lens will give a less than perfectintersection of the rays emanating from a luminous object point even on the optical axisdue to spherical aberration. The only exception are the aplanatic lens points [1,2].Additional aberrations such as coma, astigmatism, field curvature and distortion occur offaxis [3]. These aberrations have to be reduced to a level dictated by anticipatedpractical uses of the system by suitable lens design. It is general practice to solvethis problem by combining several lens elements in a system. Aspheric surfaces also offerattractive solutions. The advantages of aspheric surfaces may be the following:" @default.
