Test Method
IRM-8752K-1
The specified electro-optical characteristics is satisfied under the following Conditions at the controllable
distance.
1. Measurement place
A place that is nothing of extreme light reflected in the room.
2. 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.
(Ee
≦
10Lux)
3. 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
λp=940nm,Δλ=50nm.
Also, photodiode is
used of PD438B (Vr=5V). (Standard light / Light source temperature 2856°K).
4. Measuring system According to the measuring system shown in Fig.-3
