The corporate name, Sigma, is a Greek letter equivalent to "S" in English. This character has been used as a sign of the total sum in mathematics. It expresses our business concept symbolized by a concert, consisting of technology, knowledge, experience and wisdom.

As archive material is recovered this area will cover the full range of past Sigma products and corporate history.

We believe that SIGMA products embody the high technology, experience and thoughtfulness of each of our staff members.

The products have been manufactured with our consolidated power at Aizu Factory equipped with the latest facilities. This plant utilizes a process production system as an "Intelligent Factory" on which all steps of production, sales and technology are focused. Now the plant has become our base of production where quality and high performance products are manufactured. We deal in a wide variety of image devices around the world. We have decided to contribute through our business achievements to the improvement of communication and the future living standards of the people in the world.
