Company information
Since its establishment in 1965, Kyoritsu Electric has built a track record in the development of original products with the theme of "the fusion of light and electronics." Since 1971, we have supplied camera measurement instruments (exposure testers, luminance meters, flash testers, shutter testers, service testers, LED light sources, collimators, etc.) developed in-house, holding a significant market share primarily among camera manufacturers. Our long-cultivated optical measurement technology has been utilized in adjustment light source devices for digital cameras and video cameras, image sensor mounting alignment measurement instruments, flash light measurement instruments, and more, contributing to quality improvement. We obtained ISO-9001 certification in 1994 and are committed to traceable manufacturing. Additionally, we take pride in having a wide-ranging presence with agents in the United States, China, Taiwan, and South Korea. Moving forward, we are determined to refine our technology as a manufacturer contributing to the optical industry.
