Behind this commitment to quality stands an equally important commitment to research. Hamamatsu is known for its research into both the basic and applied aspects of the science of light. Working in our labs and through collaborative partnerships with a variety of research organizations, Hamamatsu sees light and its research not only as a springboard for new knowledge and technologies but for the improvement of life itself. This philosophical commitment to research is backed by a strong financial commitment. Over a five year period the company’s overal ratio of R&D expenses to net sales averaged 13%.
