Optical Engineering, 1975
The state of the art in manufacturing large one piece metal mirrors has advanced dramatically in the past 10 years, following important pioneer work by NASA's Jet Propulsion Laboratory in 1965. Since that time, several additional large solar simulator mirrors have been manufactured.

Ion beam smoothing of metallic mirrors
Materials Science and Engineering, 1987Abstract The implantation of 150 keV molybdenum ions into molybdenum mirrors and 400 keV silver or copper ions into copper mirrors is found to increase the reflectivity of these mirrors. Analysis of ellipsometric data from these samples using the Bruggeman effective medium approximation demonstrates that the change is due to smoothing of the surface.

Metal buffer layer inserted switchable mirrors
Solar Energy Materials and Solar Cells, 2008Thin buffer layers of hydrogen diffusive metals such as Ti, Nb, and V were inserted between a Mg4Ni thin film and a Pd top layer, which were prepared by DC magnetron sputtering. Their optical, electrochemical properties, and switching durability were investigated using both gasochromic and electrochromic switching methods.

Design and Mounting of Metallic Mirrors
2018The discussion in this chapter begins in Section 10.2 with some general considerations of metal mirrors as distinguished from nonmetallic ones. A variety of examples of metal mirror design and fabrication techniques are then discussed. Mirrors made of various materials are considered in Sections 10.3 through 10.5.

Residual infrared absorption in metal mirrors
Soviet Journal of Quantum Electronics, 1988An analysis is made of the physical factors that limit the reflectivity of mirrors in the infrared range. It is shown that the mechanism responsible for the finite residual absorption is the electron–phonon interaction in the presence of a photon (Holstein–Gurzhi effect).

Lapping metal mirror at high speed
SPIE Proceedings, 2000This paper discusses lapping a metal mirror with solid abrasives at high speed. In this method there are three procedures. First the workpiece is ground in a grinding machine, which makes the surface roughness of the workpiece reach about Ra1.6micrometers .

Processing Metal Mirrors for Dimensional Stability
Workshop on Optical Fabrication and Testing, 1981The metal mirror processing methods used today frequently produce mirror surfaces with "locked-in" stresses that eventually lead to expensive surface rework for a finished optical product. This paper focusses on the optical fabrication process where improvements in mirror blank manufacturing can be made which produce stable optical surfaces operable ...
