          *1 The range is obtained by measuring KEYENCE's standard target (ceramic).
          *2 When the sampling rate is 20 µs, the range becomes -230 mm -9.06" (NEAR side) to -250 mm -9.84" (NEAR side) for Diffused reflection.
          When the sampling rate is 20 µs, the range becomes -230 mm -9.06" (NEAR side) to -249 mm -9.80" (NEAR side) for specular reflection.
          When the sampling rate is 50 µs, the range becomes -125 mm -4.92" (NEAR side) to -250 mm -9.84" (NEAR side) for Diffused reflection.
          When the sampling rate is 50 µs, the range becomes -125 mm -4.92" (NEAR side) to -249 mm -9.80" (NEAR side) for specular reflection.
          *3 All are calculated at F.S. = ±250 mm ±9.84".
          *4 "High accuracy range" and "long range" refer to the linearity when those ranges are used.
          *5 The range is obtained by measuring KEYENCE's standard target (ceramic) with the Standard mode.
          *6 The range is obtained by measuring KEYENCE's standard (SUS) with 4,096 times of averaging at the reference distance.
