Hamamatsu S9066-211SB Spectral response close to human eye sensitivity

The S9066-211SB photo IC has spectral response close to human eye sensitivity. Two photosensitive areas are made on a single chip. One is for detecting light in the visible to near infrared range and the other is only sensitive to near infrared light and used for output signal correction. Almost only the visible range can be measured by finding the difference between the two output signals in the internal current amplifier circuit. Compared to previously available devices, this photo IC offers lower output fluctuations for light sources producing the same illuminance at different color temperatures.

Features
-Spectral response close to human eye sensitivity is attained without using visual-compensated filter.
-Operation just as easy to use as a photodiode
-Large output current equivalent to phototransistors
-Lower output-current fluctuations
-Excellent linearity
-Low output fluctuations for light sources producing the same illuminance at different color temperatures
