Recently, luminance and chromaticity management of FDD, Automotive instruments, Fluorescent substance and optical device has been increased. Especially, the needs for more measured weak optical signal and faster instrument are growing. We achieve with high chromaticity and measuring speed at BM-5AC, compared with current model BM-5AS. |
