Megal Вђ“ Mirror -

Metal mirrors serve as a critical alternative to traditional glass-based optics, offering unique advantages in mechanical stiffness, thermal conductivity, and lightweighting potential. This paper reviews the fundamental principles of metallic reflection, modern fabrication techniques such as additive manufacturing (AM), and their specialized applications in infrared imaging and space telescopes.

The production of metal mirrors has evolved from ancient handcrafted alloys to high-tech vacuum deposition and 3D printing.

Abstract

: In some Indian communities, a 500-year-old tradition uses a specific alloy of tin and copper, melted at 1200 degrees and polished with coconut oil.
