CeNing Optics is a professional manufacturer of optics. It manufactures high-quality optical lenses including singlets, doublets and cylindrical lenses. It manufactures lenses not only in standard design but also custom design. With thousands of manufacturing tools in-house and advanced manufacturing technology, it can manufacture optical lenses in a short time but at low cost. It is able to take customer projects from prototype all the way


through to volume production. The available materials include popularly used glass like BK7 and fused silica, and optical glass from Schott, CDGM and Ohara. The lenses’ diameters range from 1mm to 300mm. It can achieve surface quality up to 10-5S/D and L/8 flatness, the centration of lenses being up to 30 arcsec. Anti-reflective coating is also available upon request. Quality guarantee is its top priority.
