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
Open data	JSON / CSV, free to cite

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.
