2008-6-1 · Aluminum is also lightweight, can be readily machined with standard tools, has high thermal conductivity, and can be alloyed with other metals to attain a high stiffness. Finally, aluminum is inexpensive and without the health concerns of beryllium, which is one alternative material for many mirror applications. Polishing aluminum optics
Athermal metal optics made of nickel plated AlSi40 - .
Metal optics is an inherent part of space instrumentation for years. Diamond turned aluminum (Al6061) mirrors are widely used for application in the mid- and near-infrared (mid-IR and NIR, respectively) spectral range. Aluminum mirrors plated with electroless nickel (NiP) expand the field of application towards multispectral operating instruments down to the ultraviolet .

Electroplated High Purity Aluminum - Alumiplate
High purity aluminum plated on 6061-T6 aluminum substrate mirrors is not susceptible to bi-metallic surface figure distortion in cryogenic or broad operating temperature ranges. As illustrated in the table, the linear CTE (coefficient of thermal expansion) of AlumiPlate ® aluminum is very close to that of 6061 aluminum alloy mirror substrates.
Advantage Of Metal Coated Mirror_Tian Cheng Optics .
2018-7-18 · Aluminum can also improve oxidation resistance and heat resistance. After the aluminum-plated electrodes are sprayed with aluminum and other composite materials, an anti-oxidation coating can be formed on the surface of the electrode, which can withstand high temperatures and reduce the unit consumption of the -making electrodes.

The Global Hawk RQ-4 sees better in the visible and infra-red spectrum with AlumiPlate aluminum coated optical mirrors. Cryogenically cooled aluminum plated optics are stable and warp free without dissimilar metals Coefficient of Thermal Expansion (CTE) mismatch.
Applications - NASA
2010-3-10 · Aluminum optics are less expensive and lighter than optics made from other pure materials. Also, nickel plating aluminum optics has drawbacks. Plating faults can ruin the optic, and the bimetal thermal characteristics of nickel over aluminum are poor, which is problematic for space and other applications with dramatic temperature swings.
Fabrication of electroless nickel plated aluminum freeform ...
Freeform mirrors can be readily fabricated by a single point diamond turning (SPDT) machine. However, this machining process often leaves mid-frequency errors (MFEs) that generate undesirable diffraction effects and stray light. In this work, we propose a novel thin electroless nickel plating procedure to remove MFE on freeform surfaces. The proposed procedure has a .
