Notes:
5. D is the distance from the sensor face to the reflective surface.
6. Crosstalk (I CK ) is the collector current measured with the indicated current on the input diode and with no reflective
surface.
7. Measured using Eastman Kodak natural white test card with 90% diffused reflecting as a reflecting surface.
