*1 For 23-inch monitors.
*2 At top speed when using a combination of measurement mode/measurement quality/lens magnification. When the line scan has a measurement pitch that is within 0.1 µm.
*3 When measuring a standard sample (standard scale) with a 20× or greater lens at an ambient temperature of 20 ± 2°C 68 ± 3.6°F. However, does not apply to the VK-X120/130 with a 100× lens.
*4 When measuring a standard sample (standard scale) with a 20× or greater lens at an ambient temperature of 20 ± 2°C 68 ± 3.6°F. However, does not apply to the VK-X120/130 with a 100× lens.
*5 When a motorized stage is mounted.
