*3 EeP represents illuminance of signal light in sync with the low level timing of output at GLout terminal.

E eD represents illuminance of DC light. For detail, see Fig. 1.

Light source: Infrared light emitting diode (λ p= 940nm )

EVP represents illuminance of signal light in sync with the low level timing of output at GLout terminal.

EVD represents illuminance of DC light. Note that the light source is CIE standard light source A.
