New Open Access Release: Kepler’s ‘Dioptrice’ — The Birth of Telescope Theory

Radboud University Press proudly presents ‘Dioptrice’, Johannes Kepler’s groundbreaking work that laid the theoretical foundation for the modern telescope. Expertly translated and introduced by Søren S. Larsen, this new edition makes one of the most important texts in the history of optics and astronomy accessible to a wider audience.

First published in 1611, ‘Dioptrice’ was the first work to explain how lenses could be combined to magnify distant objects — a theory still relevant in today’s optical sciences. It introduced the design of the Keplerian telescope, further developed Kepler’s account of the physics of vision, and coined the term dioptrics, still in use today.

This landmark publication offers scientists, historians, and curious readers a window into the early scientific revolution — and Kepler’s unparalleled ingenuity.

‘Dioptrice’ is now available online for free (open access). The paperback version is available for €36,-
