Glass Analysis

Glass analysis is about reading an installed unit in place, without taking it out: its build-up — pane count, pane thickness and cavity width from one accessible side — whether a low-emissivity coating is present and which numbered surface carries it, or whether a pane is thermally toughened rather than annealed or laminated. Each is a different measurement problem, answered by a different method under a different standard. Pin down which of those your survey needs to settle, and that decision narrows the field to a single meter.
