LK-G505/LK-G500
*1
The value when measuring the KEYENCE standard target (ceramic) in the standard mode. When the sam-
pling rate is 20 µs, the value becomes –230 (NEAR side) to –250 mm (NEAR side) at the time of the diffuse
reflection, and –230 (NEAR side) to –249 mm (NEAR side) at the time of the specular reflection. When the
sampling rate is 50 µs, the value becomes –125 (NEAR side) to –250 mm (NEAR side) at the time of the
diffuse reflection, and –125 (NEAR side) to –249 mm (NEAR side) at the time of the specular 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
reference distance.
