Optical systems with remote pupils (OSRP) are widely used in modern optical devices. The following systems can be mentinoned as examples of OSRP

• remote-pupil objectives used in combination with prisms and mirrors in viewfinders and scanning devices
• remote-pupil lens for mathing pupils (e.g. field lens in telescopes)
• eyepieces
• component of the inverting systems

The distinctive feature of the OSRPs is a significant offset of the entrance (or exit) pupil from the optical system. This offset may exceed the focal length of optical system. Such asymmetry of construction complicates design and aberration correction of remote-pupil systems, especially when field of view and aperture are large. The main difficulties are growing lens diameters, vignetting of oblique beams and correction of the odd aberrations (coma, distortion and lateral color)

Meanwhile, the opportunities for use of remote-pupil optical systems are so attractive that there is a challenge of development basic designs of OSRP. The solution of this problem can be found by the synthesis of optical system from optical components, which have known aberration characteristics (prototypes). The concept of this method is given in Powerpoint presentation.
