1. A method for setting up one or more ranges of one or more inspection parameters in an optical inspection system, the method comprising: (a) receiving a set of values of an inspection parameter, wherein the set of values corresponds to set-up areas of a set-up image obtained from a sample; (b) constructing a test image comprising multiple test areas such that locations of the test areas corresponds to locations of the set-up areas and such that colors of the test areas are determined by corresponding values in the set; (c) displaying the test image and a range diagram on a user interface of the optical inspection system, wherein the range diagram corresponds to the inspection parameter and comprises a nominal limit and a variation limit, wherein the nominal limit and the variation limit define a range corresponding to a color that does not overlap with an outside range corresponding to an outside color, and wherein the test areas have the color if the corresponding values in the set fall within the range or the outside color if the corresponding values fall within the outside range; (d) receiving an adjustment of the variation limit and/or the nominal limit based on the test image; (e) repeating (b)-(d) until the test image reaches predetermined criteria; (f) receiving a second set of values of a second inspection parameter, wherein the inspection parameter and the second inspection parameter are different types of inspection parameters, wherein the second set of values corresponds to the set-up areas of the set-up image or a second set-up image obtained from the sample; (g) constructing a second test image comprising multiple second test areas such that locations of the second test areas corresponds to location of the set-up areas and such that colors of the second test areas are determined by determined by corresponding values in the second set; (h) displaying the second test image and a second range diagram on the user interface of the optical inspection system, wherein the second range diagram corresponds to the second inspection parameter and comprises a second nominal limit and a second variation limit, wherein the second nominal limit and the second variation limit define a second range corresponding to a second color that does not overlap with a second outside range corresponding to a second outside color, and wherein the second test areas have the second color if the corresponding values in the second set fall within the second range or the second outside color if the corresponding values fall within the second outside range; (i) receiving an adjustment of the second variation limit and/or the second nominal limit based on the second test image; (j) repeating (f)-(i) until the second test image reaches predetermined criteria; and (k) setting two or more ranges for the inspection parameter and the second inspection parameter in the optical inspection system based on the variation limit and the nominal limit corresponding the test image at the predetermined criteria and based on the second variation limit and the second nominal limit corresponding the second test image at the predetermined criteria.
