Lighting (brightness / color monitor)

Brightness detection sensors including illuminance sensors are used for dimming and automatic operation of lights according to their surroundings, as well as for dimming backlights of LCDs. Hamamatsu offers a wide variety products, including phototransistors that simply detect when surroundings have become dark, illuminance sensors with a spectral response close to human eye sensitivity, as well as color sensors and spectroscopic sensors suitable for applications such as measuring both brightness and color temperature.
