Test Method:
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
cMeasurement place
A place that is nothing of extreme light reflected in the room.
dExternal light
Project the light of ordinary white fluorescent lamps which are not high
Frequency lamps and must be less then 10 Lux at the module surface.
(Ee≦10Lux)
eStandard transmitter
A transmitter whose output is so adjusted as to Vo=400mVp-p and the output
Wave form shown in Fig.-1.According to the measurement method shown in
Fig.-2 the standard transmitter is specified.
However , the infrared photodiode to be used for the transmitter should be
λp=940nm,∆λ=50nm. Also, photodiode is used of PD438B(Vr=5V).
