LK-G15/LK-G10
*1 When the sampling rate is 20 µs, the value becomes +0.37 (FAR side) to –1 mm (NEAR side) at
the time of the diffuse reflection.
*2 The value when measuring the KEYENCE standard target (ceramic) in the standard mode
*3 The value when measuring the KEYENCE standard target (SUS) 4096 times average at the refer-
ence distance.
The value in parenthesis ( ) indicates the typical value when measured with the number of aver-
aging times of 16384.
