Stage Specification Comparator

Positioning stage datasheets use inconsistent units and mixed specification conventions that make direct comparison difficult: travel may be in mm or inches, resolution in nm or arc-seconds, repeatability specified unidirectionally or bidirectionally, and accuracy with or without software calibration. This tool normalizes up to six stages to common units — µm for linear error specs, µrad for angular errors, N for load — and displays them in a side-by-side table with the best value per parameter highlighted. Warning flags fire automatically when stages use incompatible calibration states for accuracy or mismatched directions for repeatability, where a direct numerical comparison would be misleading. Drive type, bearing type, and encoder type can be entered as qualitative descriptors alongside numeric specs. Resolution listed without a minimum incremental motion (MIM) value also triggers a warning, since encoders can resolve finer than the stage can actually move.
