M OST HISTORIES OF SCIENCE give simplistic and misleading accounts of the invention of the reflecting, or catoptric, telescope.' Its creation, we are told, is mostly due to Isaac Newton, who, drawing the inspiration from an earlier suggestion by his countryman James Gregory,2 constructed his first reflector in 1668. Newton, the usual accounts say, on discovering the composite nature of white light, wrongly believed that further development of the refracting, or dioptric, telescope was… 

The Beginnings of Commercial Manufacture of the Reflecting Telescope in London

The reflecting telescope emerged into the public gaze (or at least into the view of the scientific community) in early 1672. The success of the diminutive telescope constructed by Isaac Newton,

James Gregory and the Reflecting Telescope

The concept of using reflecting optics for constructing a telescope had clearly been appreciated in early seventeenth century continental Europe, and there are grounds for believing that experimental

Optical reflection and mechanical rebound: the shift from analogy to axiomatization in the seventeenth century. Part 2

Thomas Harriot, whose work was discussed in the first part of this paper, generalized the kinematics and dynamics of optical reflection to form the foundations of an atomistic theory of impact.1 What

Engineering interests and inventions of Isaac Newton

The paper presents engineering interests of Isaac Newton, including some of his technical inventions. So far, this topic has not been studied in a broader manner and in more depth. This article

Planar focusing reflectors based on monolithic high contrast gratings: design procedure and comparison with parabolic mirrors.

It is concluded that the phase of the hyperbolic phase of these mirrors does not have to be perfectly mimicked to obtain a focusing reflector and planar focusing grating mirrors offer a good alternative to parabolic mirrors.

ABCD transfer matrices and paraxial ray tracing for elliptic and hyperbolic lenses and mirrors

A method is introduced for evaluating the ABCD transfer matrices for paraxial rays refracted/reflected by lenses/mirrors with elliptic or hyperbolic surfaces, which relies on the use of certain cusp

Relecture mécanologique de l’histoire des télescopes
