Introduce
- 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.
Feature
- 5 steps selectable measurement angle.
- Built-in analog output, it can be data collect a data with a oscilloscope.
- High speed response speed 0.05ms (Max).
It can measure the object from particle area to wide area without attachment lens.
Building up and falling down time of the flicker light can be measured using Oscilloscope.
Application
- Measurement luminance and chromaticity.
– TV, PC, Tablet, Smart phone display. – Ultra micro spot for automobile interior panel. – Fluorescent material, phosphorescence material, special light source.
