光洋産業 List of Products and Services

We measure the electromagnetic environment of buildings such as companies, factories, and hospitals, which may be concerned about equipment malfunction or health hazards to humans due to electromagnetic wave interference. We also offer measurements of the shielding effectiveness at installation sites for MRI and CT machines, as well as surrounding electromagnetic environments. 1) Magnetic Field Measurement When it is necessary to know the magnetic field environment in advance, such as for the installation of devices that are susceptible to magnetic field influences, please make use of our environmental measurement services. 2) Examples of On-Site Measurements - Installation sites for electron microscopes - Installation sites for semiconductor manufacturing equipment - Installation sites for hospital equipment and testing devices - Near power transmission lines - Near transformers - In areas around apartment buildings or residential construction sites where there are nearby power transmission lines or substation facilities 3) Classification of Environmental Magnetic Fields - DC Magnetic Fields Magnetic fields leaking from permanent magnet application devices (such as speakers), magnetic fields generated by DC large currents from lightning or welding machines, strong electromagnets (such as lifting magnets), and geomagnetic fields. - AC Magnetic Fields Magnetic fields from power transmission lines and substation distribution equipment at commercial frequencies. - Fluctuating Magnetic Fields Transient magnetic field changes caused by the passage of trains or vehicles, disturbances in magnetic fields due to the operation or shutdown of electrical equipment and devices.

● We offer on-site measurement and testing services for electromagnetic wave environments to resolve the issues you inquired about. ● From the pre-meeting of the planning stage, we provide a one-stop solution that includes on-site measurements, consulting based on the results, and subsequent electromagnetic wave countermeasures and shielding construction. ● We will also propose more cost-effective and efficient materials and construction methods.

We offer a one-stop solution for the development of electromagnetic wave shielding materials at our in-house research institute, manufacturing at our own factory, measuring materials and methods in our in-house research facility's "anechoic chamber," design, electromagnetic wave shielding construction, and electromagnetic wave measurement (upon handover).
