WDmax

WDmax is a term used across several technical disciplines to denote a maximum constraint involving width or distance, depending on context. It does not refer to a single standard, and definitions vary by field or by organization.

In optical engineering and microscopy, WDmax often stands for maximum working distance—i.e., the largest distance from the lens to the specimen at which a given imaging performance is achievable. WDmax influences specimen accessibility, illumination, and depth of focus, and objective manufacturers publish WDmax values for their lenses.

In computer-aided design and geometry, WDmax may describe a maximum width constraint in layout or modeling problems, where widths of features must not exceed specified limits to satisfy manufacturing or assembly constraints. The exact meaning is defined in product docs or a modeling framework.

In data analysis and signal processing, WDmax can be a parameter representing the maximum width of a window, segment, or feature, used in algorithms that scan signals or images for patterns. As with other uses, WDmax must be defined in the relevant methodology section.

Because the term is not standardized, readers should consult the source material for the precise definition of WDmax in a given document. See also working distance, width constraint, and parameterization in technical specifications.
