Modern telescope developments: pupil segmentation and techniques to reduce mass,1980. From about this time, the evolution of telescope optics, which had retained certain essential features ever since Galileo’s telescopes in 1610, was supplanted by a .. A summary of this process was recently given by the author .

Mirror Reflecting Coats: Production and Cleaning, be reduced by anti-reflection coating. Absorption is often a serious problem in the UV unless fused silica can be used but is otherwise usually a minor loss. The most serious source of reduction of τt is therefore the reflectivity of mirrors, above all if there are a significant number in the optic

Image quality specification and optical efficiency criteria,wave theory of light by Young, Fresnel and Fraunhofer. This led in 1879 to the first formulation by Rayleigh of optical tolerances as a . of the wavefront (see § 3.10.5 of RTO I), leading to the rough general rule that a system was still effectively diffraction limited provided the wavefront error did not exceed λ/4 (.).
