In the near future many large optics are required for astronomy and space applications. The use of computer controlled optical surfacing provides a way to meet this challenging requirement. This paper describes such an automated fabrication operation, the process, and equipment. Also, the automated fabrication of six large aspheric optics is reported.

Recent advances in the application of infrared spectroscopy to the study of magnetic disk surfaces with regard to analysis of lubricant thickness, extent of coating oxidation, impurities present, etc. have been shown to be useful in that the analysis need not be performed in a vacuum apparatus nor need the sample be destroyed. The infrared approach in the above applications has in many cases been reduced to useful empirical methods, but the technique typically relies on the superior throughput and sensitivity of Fourier transform infrared spectrometers (FTIR). Due to the advent of readily obtainable FTIR spectrometers, it is now possible to take infrared spectra of monolayer amounts of molecules adsorbed on surfaces.

This paper will trace the development of a hard gold electro-deposited coating that was originally developed to solve an engineering problem for Xerox. The plating bath variables that were considered and those that were eventually decided upon will be treated. Test procedures and results for both hardness and reflectance will be illustrated. Applications of this gold coating for mirrors, reflectors, integrating spheres, and diffraction gratings will be discussed. Design considerations, such as its ability to be deposited over glass as well as metal substrates and its diamond machine ability, will be touched upon.

Factors involved in installation, use, and maintenance of optics in "remote" locations and adverse environments are discussed in terms of what should and shouldn't be designed and built to make life easier for those who are destined to use and maintain them. Factors requiring consideration include, but are not limited to, distance from competent assistance, the limited competence of locally available assistance, the limited quantity and nature of test and handling equipment at many field sites and the less-than-ideal environment in which many systems must survive and produce hopefully ideal results.

In many systems applications, mirror materials are needed that have, in addition to a good optical surface, high thermal conductivity, light weight, a low thermal expansion coefficient, rigidity, toughness, or other combinations of properties not available in conventional glass or fused quartz optics. Metals, ceramics, semiconductors, and other materials have been considered for mirror substrates. The requirement of an extremely smooth, low scatter surface has spurred a large effort to learn how to polish several unconventional materials, and good results have been achieved in some cases. We will describe in detail the polishing of two of these materials, silicon and molybdenum, and will also mention others. Differential interference contrast (DIC) micrographs and surface profiles of selected materials will be shown, along with rms roughness values obtained from total integrated scattering (TIS) measurements and roughnesses measured directly with a surface profiling instrument.
