AbstractThe full potential of the next generation of larger telescopes will be realized only if they have well instrumented large fields of view. Scientific problems for which very large ground-based optical telescopes will be of most value often will need surveys to very deep limits with imaging and slitless spectroscopy, followed by spectroscopy of faint objects taken many at once over the field. Improved instruments and detectors for this purpose are being developed. Remotely positioned fibers allow the coupling of light from many objects in the field to the spectrograph slit. CCD arrays, operated in the TDI or drift scan mode, will make large area detectors of high efficiency that may supercede photographic plates. An ideal telescope optical design should be based on a fast parabolic primary, have a field of at least 1° with achromatic images < 0.25 arcseconds and have provision for dispersive elements to be used for slitless spectroscopy and compensation of atmospheric dispersion over the full field. A good solution for a general purpose telescope that can satisfy these needs is given by a three element refractive corrector at a fast Cassegrain focus. A specialized telescope dedicated to sky surveys, with better image quality and higher throughput than presently available, might be built as a scaled up Schmidt with very large photographic plates. Better performance in most areas should be obtained with a large CCD mosaic detector operated in the drift scan mode at a telescope with a 2-mirror reflecting corrector.

Atmospheric dispersion produces spectral elongation in images formed by land-based astronomical telescopes, and this elongation increases as the telescope points away from the zenith. Atmospheric Dispersion Correctors (ADCs) produce compensating dispersion that can be adjusted to best cancel out the atmospheric effect. These correctors are generally of two basic types: Rotating Atmospheric Dispersion Correctors (R-ADCs), and Linear Atmospheric Dispersion Correctors (L-ADCs). Lately, a third type, the “Compensating Lateral ADC” (CL-ADC) has been proposed. None of these design approaches allow for large corrector systems (with elements greater than 1 m in diameter), in which the secondary spectrum is corrected to small residuals, of the order of tens’ of milliarcseconds. This paper describes a new type of large corrector (>1 m diameter elements), which can achieve the correction of the secondary spectrum to the order of 10 milliarcseconds. This correction is achieved by combining the R-ADC and CL-ADC approaches to dispersion correction. Only glass types readily available in metre diameters are required.

Charles Gorrie Wynne dedicated his professional life to optical design and became a principal figure in the international optical design community. When he died, he was optical consultant to the Institute of Astronomy in Cambridge and Emeritus Professor of Optical Design at Imperial College. Although nearly 90 years old he worked several days a week in the Institute of Astronomy until a few months before he died. He was elected to Fellowship of The Royal Society in 1970. Wynne's expertise was in the field of optical instrument design, particularly lens design. Among lens designers he is best known for his effective theories of lens design, his elegant and ambitious lens designs, and particularly his invention of a very successful method of computer-assisted lens design, based on the method of least squares. Among astronomers he is known for what is almost a monopoly of designs for field–widening optics for large telescopes, and also for a series of scientifically elegant spectrographs and atmospheric dispersion correctors. With microcircuit manufacturers he is famous for his work on the Wynne–Dyson catadioptric relay printer for microcircuit production. By high–energy physicists he is known as the designer of bubble–chamber optics; finally, he is known by his assistants and his students as their professional mentor. During the formative period of Charles Wynne's working life, optical design was performed almost exclusively behind the closed doors of optical factories. The optical designers in those factories traditionally led a monastic working life, closeted with a few close colleagues and assistants, grappling with the extensive numerical calculations that optical design involves. During the period of his career when he worked in this way, he managed to combine this type of working life with creative original research into new types of lens system and new methods of lens design.
