Every ERDI laser rangefinder, specified honestly
59 models — 905 nm and 1535 nm rangefinder modules, single-point LiDAR distance sensors and erbium-glass laser sources — in one filterable table, with the manufacturer's test conditions printed next to every range figure and no prices hidden behind a form.
What this site is
A specification and selection resource for engineers choosing an OEM laser rangefinder. It is maintained by the supplier side, and it is deliberately boring about the things that decide a programme: what the range figure was measured against, what the accuracy figure includes, what the interface actually is, and what the safety statement covers.
| Rangefinder modules & LiDAR sensors | 47 models, 9 m to 23 km published range |
|---|---|
| Laser sources (1535 nm) | 12 models, 100 µJ to >10 mJ |
| Mass range | 1 g to 410 g |
| Interfaces | UART/TTL, RS-422, RS-232, CAN, discrete trigger |

Where to go next
Selection guide
Six decisions in the order that constrains the answer: wavelength, target, accuracy, rate, interface, envelope.
1535 nm vs 905 nm
Why one reaches 23 km and the other weighs 1 g, and what "eye-safe" does and does not cover.
Interfaces
UART vs RS-422, trigger timing, inrush, aperture and window — the parts that break integrations.
Applications
Drone gimbals, border surveillance, thermal integration, industrial sensing, sport optics.
FAQ
Eight questions that decide whether a module fits.
