SiC aspheric mirror

  SiC(silicon carbide) material has become a new strategy for large mirror fabrication and has been widely used in large aperture space telescope systems.MG Optics manufactures lightweight SiC mirror range from 50 mm to 2000mm. 1/100 RMS or better.     Product Specification FEATURES SPECIFICATIONS Material Options SiC Size 50mm-2000mm Surface Accuracy 1/100 RMS or better Roughness Up to 1nm Coating Al, Ag, Au & High Laser Damage Threshold Dielectic as needed Design Services Optical, FEA, Dynamic & Thermal Analysis We can provide customized service according to specific customer requirements.   Product Properties Compared with ULE and other metal materials, silicon carbide (SiC) has outstanding advantages in specific stiffness, and is easy to achieve the light weight of the mirrors. The mirror blank made of silicon carbide is about 2 times lighter than ULE material. SiC material has high thermal stability, r…
