OVD deposition equipment is important equipment for manufacturing the outer cladding of optical fiber preforms. OVD technology primarily deposits silicon oxide on a substrate to form the optical properties and structural characteristics required for optical fibers. OVD deposition equipment plays a crucial role in optical fiber production, using an efficient, precise deposition process to meet the requirements of modern optical communications and sensor technologies. Equipment components: deposition chamber: 1 set; evaporation cabinet: 1 set; gas cabinet: 1 set; exhaust-gas treatment unit: 1 set; electrical control system: 1 set.
