How is Precision Measured in Nanotechnology Instruments?
Precision in nanotechnology instruments is often quantified in terms of resolution, accuracy, and repeatability.
- Resolution: This refers to the smallest detectable feature size that an instrument can differentiate. For example, an AFM might have a resolution of 0.1 nanometers. - Accuracy: This indicates how close the measured value is to the true value. High accuracy ensures that measurements reflect the real characteristics of the sample. - Repeatability: This is the instrument's ability to produce the same results under unchanged conditions. High repeatability means that multiple measurements of the same sample will yield consistent results.
