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 |

Reference tables (the part engineers bookmark)
Range conditions
Every published range figure beside the target, reflectance and visibility it was measured against — verbatim.
Interfaces
UART-TTL, RS-422, RS-232, CAN: which model has what, the manufacturer's wording, supply and mass.
Optics
Divergence, receiver aperture, pulse energy, update rate — with the spot diameter each divergence produces at 1 km.
By application
Six job profiles with the models that fit and the selection rule written down, so you can judge it.
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.

One email, datasheet and price for your configuration.
