^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 a motorized stage is mounted.
