🔍 Telecentric lenses: When a fraction of a millimeter matters.
The same part, with the same drawing, can produce different measured widths if its height changes in the fixture.
A conventional lens can turn this height variation into measurement error. A telecentric lens helps minimize magnification changes over its specified working-distance range, supporting more consistent dimensional measurement.
📊 What should you check when choosing a telecentric lens?
