World's top brand optical equipment and peripheral products


In pursuit of world-class technologies and products

At T.E.M. Incorporated (TEM), our mission is to always provide the latest world-class technologies and products to customers in the optical-equipment industry, an industry where technical innovation proceeds rapidly.


    Our mission is to provide the latest Western, laser-related products to customers in Japan’s optical-equipment industry in a timely and high-quality manner. To accomplish that mission, we at TEM continually meet the needs of customers by drawing on our solid customer-support system and high technical skills.
    In particular, we place an emphasis on resolving the quality problems and support difficulties that often represent risks when a company is putting into operation products made overseas. We possess the systems and technology necessary so that customers can put these products into operation with peace of mind, and we continually draw on our systems and technology to meet the needs of customers.


    At our technical center, we do everything necessary so that our customers can use foreign-made products with peace of mind, from maintaining an inventory of products and inspecting products on arrival to inspecting outgoing shipments, providing technical-development support, and carrying out follow-up service.
    We also continuously research the latest technologies and products, and we are therefore able to propose products that meet the market’s needs.
