Paper Abstract

For optical systems with smaller field angle the correction of spherical aberration is advanced. For such systems the use of aspherics allows either improvement of image quality or reduction of the number of lens elements required to achieve the aforegiven image quality. Optical systems in the visible spectral region used for technical applications like optical data processing can be attached to this type. Here the use of aspherics is advantageous. By reducing the number of elements veiling glare can also be minimized. When observing systems in the infrared spectral region with not too large a field angle, the use of aspherics makes the corrections easier. This is important because in the infrared region only a few optical transparent materials are available. The possibility to reduce the number of elements allows the reduction of weight of the whole system. Typical aspherics for such systems in the visible and the infrared spectral region are shown and their advantages demonstrated. The required accuracy of these aspherics is specified.
