- 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
LRF0105C 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 see datasheet and the documented supply is DC3～5 V. 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 1535 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.
