Zerodur mirror blank

Zerodur is the primary material used due to its low coefficient of thermal expansion (CTE), which ensures that the mirror's shape remains stable even under varying environmental conditions,  its characteristics make it an ideal material for precision Optical Components such as telescope mirrors. MG-Optics provide Custom Zerodur mirror blank for large astronomical telescopes where maintaining precise Optical Alignment is critical for high-quality imaging and spectroscopic analysis. The maximum size is 1500mm.

 When designing large-diameter mirrors, we must fully consider lightweight and flexible support. We must comprehensively consider factors such as material characteristics, processing technology, and material costs to select appropriate materials and adopt optimal lightweight methods in the structural design. MG-Optics provide custom back structure design and process to achieve the optimal combination between lightweight rate,structural stability and overall manufacturing cost.
