VOUT
When standard transmitter output the signal at Fig.1 standard photodiode output become io=5
Ap-p under the
measurement condition Fig.2.
(The radiant intensity of standard transmitter : 50mW / sr)
RPM-302B : standard photodiode has short current Isc=27
A at E=1000(lx)
(using CIE standard light source A)
