In-line colorimeter BM-5AC

for color analysisfor displaysfor laboratories

Recently, luminance and chromaticity management of FDD, Automotive instruments, Fluorescent substance and optical device has been increased. BM-5AC is a high sensitivity luminance colorimeter combines high reliability, operability and high speed. ￭ 5 steps selectable measurement angle. It can measure the object from particle area to wide area without attachment lens. ￭ Built-in analog output, it can be data collect a data with a oscilloscope. ￭ High speed response speed 0.05ms (Max). Building up and falling down time of the flicker light can be measured using Oscilloscope. Principal use ￭ Measurement luminance and chromaticity. – TV, PC, Tablet, Smart phone display. – Ultra micro spot for automobile interior panel. – Fluorescent material, phosphorescence material, special light source.
