- Mid-range targeting, surveying and vehicle-mounted observation.
- Gimbal and sight integration where a few kilometres of usable range is the design point.
- Systems that need eye-safe 1535 nm operation at a modest size and mass.
Integration notes
LRF3000A1 is a bare module, not a finished instrument: it arrives with an electrical interface and a mechanical envelope, and your product owns the optics, the housing and the safety case. The documented interface is UART, 3.3 V TTL and the documented supply is 3.3–5 V DC. Where a figure above is a limit (≤ / ≥), treat it as the manufacturer's statement and confirm the acceptance test in your own build rather than assuming margin.
For a 905 nm rangefinder, the laser safety classification of the finished product is the integrator's responsibility: the module document states its own classification, and the accessible emission of your assembled unit must be assessed separately.
How LRF3000A1 differs from LRF0105C
