Aiming for maximum quality in a "micro world"

Due to the nature of the product in question, it was considered impossible to completely eliminate ghosting. As a result of her initial internal investigation, Fujikawa also found that the frequency of the bright ghost, which had been reported, was quite low. The supplier agreed that the level of quality was not an issue. However, this was not the end of the challenge. Fujikawa promised further improvements. She asked herself, “When did the discrepancies start and what was the root cause?”


“We did everything we could to find out, conducting a full survey, running simulations using optical analysis tools, and compiling information for future countermeasures,” she explains. During repeated hypothesis testing and trial-and-error sessions, Fujikawa always kept the following philosophy in mind: “As a manufacturer, we must never inconvenience our customers.”

Coordinating her efforts with many sections including production technology, quality assurance, as well as affiliated companies, Fujikawa made steady progress toward quality stabilization. As a result, she succeeded in establishing a more stable and higher-quality production system. From the world of optics to the world of radio waves, Fujikawa is taking on challenges in diverse new fields. While working on camera components, she helped to improve mass production quality and contributed to the design and development of lenses for new products. Currently, in the Research and Development Division, she is focused on the design and development of dielectric lenses for millimeter-wave lens antennas. Her experience in production quality control will likely be a major stepping stone toward the commercialization of dielectric lenses. Her next big challenge.
