TEST METHOD
The specified electro-optical characteristics is satisfied under the following
Conditions at the controllable distance.
Measurement place
A place that is nothing of extreme light reflected in the room.
External 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.
(Ee10Lux)
Standard 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
p=940nm,
=50nm. Also, photo
diode is used of PD438B (V
R
=5V).
(Standard light / Light source temperature 2856
K).
Measuring system
According to the measuring system shown in Fig.-3
