Fused silica JGS2 mirror

MG-Optics has rich experience in custom precision optical components manufacture and metrology.  Fused silica JGS2 aspheric mirror is commonly used in telescope mirror systems. Large aperture JGS2 mirror is one of our main products, the diameter can reach 2000mm. We can also design and manufacture custom CGH for optical metrology, surface accuracy can achieve 1/100 wavelength or better. Material Description JGS2 fused silica material has been one of the best choices for astronomical telescope mirrors with its cost-effective price and stable optical performance.
