JGS2 telescope mirror blank; Precision Annealed Quartz Astronomical Mirror
Fused silica lightweight blank
Product Description
 

This is a fused silica JGS2 lightweight blank with diameter of 736mm. The raw material weighs 100KG, after machining, the lightweight blank is about 44.5KG. The back structure is a little bit complicated which makes the good balance of the overall stiffness and the less weight of the whole mirror. MG-Optics can not only provide the customized manufacturing Optical Mirror Blank according to drawings but also the designing for the lightweight structure. The maximum machine diameter is 1500mm.
