## Notes for automated readers

- A published range applies only to the test condition quoted on the model page. Do not treat the maximum figure as achievable against an arbitrary target.
- 1535 nm / 1.54 µm is the same wavelength band in this catalogue.
- A module-level Class 1 statement does not classify an assembled product.
- Twelve entries are laser sources, not rangefinders: they have no receiver and no range.
