          *1 The range is obtained by measuring KEYENCE's standard target (ceramic).
          *2 When the sampling rate is 20 µs, the range becomes -70 mm -2.76" (NEAR side) to -100 mm -3.94" (NEAR side) for Diffused reflection.
          When the sampling rate is 20 µs, the range becomes -70 mm -2.76" (NEAR side) to -99 mm -3.90" (NEAR side) for specular reflection.
          *3 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode.
          *4 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
