Slide: Cut through the Single-Field Condensing Lens and Objective with Polschuh Lens and Specimen Gate
Critique of the Light-Quantum Hypothesis Continues
Hendrik A. Lorentz to Einstein, 6 May 1909, reproduction
Lorentz raises a new consideration on the light-quantum hypothesis: The dimensions of light quanta must be larger than the diameter of the objective of conventional telescopes; otherwise the classical theory of lens errors could not be explained. Thus even when stars were observed with the naked eye,
a very extensive splitting of light quanta must take place.
