Characteristic value
Lusterless paper with an OD of 0.7 max. (sensing distance: 80 mm) (see note)
120 mm (from the top of the sensor), OD: 0.05
80 mm (from the top of the sensor)
Sunlight: 3,000 lx max., fluorescent light: 2,000 lx max.
Note: 1. The data shown are initial data.
2. Optical darkness (OD) is defined by the following formula:
OD = − log₁₀
POUT
PIN
P_IN (mW):Light power incident upon the document
P_OUT (mW):Reflected light power from the document
■ Optical Path Arrangement
10 dia. (see note 1)
120 (see note 2)
80 (Standard value)

Glass
Note: 1. The part with oblique lines indicates the paper sensing area of the EY3A-1081, which is practically determined by the diameter of the
beam and its tolerance.
2. The non-sensing distance of the EY3A-1081 is determined using a paper with an OD of 0.05.
