A family of two-mirror correctors has been devised in a more advanced form than that obtained by Paul in 1935. These correctors can be used in combination with any paraboloidal telescope of even the largest size and will yield a greatly enlarged photographic field without the need for refracting elements of any kind. Such correctors will be of particular use in the ultraviolet, and for space-borne telescopes into the far ultraviolet, with performance limited only by diffraction over angular… 

New developments in telescope design

Abstract The present surge in the building of telescopes of more than 6 m aperture far surpasses even the efforts of the 1970s when several 3·5-4 m telescopes were built. Early in the next century,

Corrector design with active vase mirrors that allows a fixed telescope to access a large region of the sky.

This work investigates a family of two-mirror correctors to compensate for the aberrations of a parabolic mirror observing at a large angle from the zenith, which can be generated with active vase mirrors.

This paper presents three optical designs based on the work of Maurice Paul. Paul's three-mirror anastigmats produce well-corrected, distortion-free fields of view. His design equations can be solved

Suitable off-axis space-based telescope designs

We describe here several off-axis designs for space-based telescope optimized for low scattered light and low emissivity. We show how the geometric optical performance can equal that of an on-axis

Three-mirror telescopes: design and optimization.

A method of optimizing the performance of three-mirror systems by varying the inputs to the design equations is described, and the results are compared with those obtained through a conventional numerical design optimization.

Anastigmatic three-mirror telescope.

A new configuration of a three-mirror telescope is introduced that combines high performance with practicality and excellent stray light suppression are the outstanding features.

Optical Design Of An Astrometric Space Telescope

A three-mirror telescope derived from the Paul corrector is described. It differs from the original Paul design in several respects. (1) The third mirror is located behind the primary mirror instead

A Study on the Paul-Baker System as an Instrument for Multi-object Spectrum Observation

Paul-Baker systems with 4◦ flat field and 5◦ flat field are studied. Their light obstructions under different f/ratios of the primary mirror are analyzed. Due to the strong f/ratio of the system, a

Very large ground-based telescopes for optical and IR astronomy

Optical and IR astronomers are taking a hard look at their ground-based facilities and devising new ways of making more economic, bigger and better telescopes. Features of instruments of the 15-m

The "plate-diagram" method of quantifying and manipulating the Seidel aberrations of an optical system has been used to develop a procedure that has successfully determined the complete solution set



Field Correctors for Large Telescopes

The aberrations of large telescope mirrors can be corrected by lens systems located near to the focal plane. The three-element systems, designed by Ross for the 200-in. (5-m) Mount Palomar telescope,


The theory of the Schmidt telescope has been based on consideration of the properties of a spherical mirror.1 It develops that a spherical mirror, in conjunction with a correcting lens of little or

Field Correctors for Parabolic Mirrors

Optical systems to correct the oblique aberrations of large parabolic mirrors in astronomical telescopes are discussed. The earlier work of F. E. Ross on doublet lens correctors in the converging

Optical Problems at the Palomar Observatory

To increase the effectiveness of the instrument, corrector lenses were designed by Ross greatly to enlarge the field of the main mirror and the method of evaporating a reflecting coat of aluminum was developed by Strong to replace the old silvering procedures.

Corrector systems for cassegrain telescopes.

Most modern reflecting telescopes have relative apertures of about f/3 and f/8 for the primary and first secondary foci in accordance with the suggestions of Bowen. The angular field which can be

The optical system for the 3.5-m ESO telescope.

The optical design of a mirror telescope with a free aperture of 3.5 m and the results of ray tracing in the form of spot diagrams are dealt with.


The fifteen years since the war have seen drastic changes in astronomical equipment and observing techniques. Photomultiplier receivers have replaced the photographic plate for perhaps one-fourth to

Anastigmatic cassegrain type telescope.

The 152-cm telescope of the Cerro Tololo Inter-American Observatory in Chile is to be made to a design producing images that are free of the usual Ritchey-Chrétien astigmatism. A 38-cm diam

Ritchey Chrétien corrector system.

This principle is employed in the design of a two element aplanatic corrector lens used with the Ritchey-Chretien form of Cassegrain optical system to correct the latter's residual field curvature and astigmatism.

Prime focus correctors involving aspherics.

Three tentative field correctors for prime focus use are described; they each have one or more aspheric surfaces.
