Fused silica lightweight blank

  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.    Material Description  JGS2 fused silica material has been one of the best choices for telescope mirror blank with its cost-effective price and stable optical performance.
