Standard plate 'ND filter' for confirming transmission linearity.
Easily verify the accuracy of measurement values from measuring instruments!
To ensure that measuring instruments operate in a consistently stable condition, various systems are incorporated within the device; however, it is unavoidable to encounter issues due to aging changes and dirt such as dust. To verify whether the measuring instruments being used can always measure a stable transmittance, a "standard plate" that consistently provides a fixed value, like this "ND filter," is necessary.

In 1947, a color research group was established in a corner of Tsukishima, Tokyo, which later became the Color Division of Japan Electronic Measuring Instruments Co., Ltd. The group focused primarily on the production of standard color samples and research and guidance on color adjustment. In November 1956, it became independent and was established as Murakami Color Technology Research Institute, Inc. Since its founding, our company has made the production of measuring instruments related to visual information processing, including "color and gloss," the production of color samples, and the promotion of color management the pillars of our business, and we have been active as a pioneer in the industry. Our market share is extremely high. We will continue to make further efforts for the development of color science and the creation of a prosperous society, and we hope to be of service to everyone.
