Board-level module · source: ERDI catalogue (1535nm_rangefinder · page 5) · no prices on this page
LRF0105C is a board-level laser rangefinder module. The figures below are transcribed from ERDI's published catalogue (1535nm_rangefinder · page 5), not from memory; fields the catalogue does not publish are listed as unpublished rather than estimated.

Where it sits in the ladder
LRF0105C sits at position 10 of 14 on the published single-unit ladder ($500). The step below is LRF600H at $350 (−$150). The step above is LRF0610C at $1,000 (+$500). This is the eye-safe branch: people can be near the beam, which is why the price per metre is higher here than on the 905 nm classes. Published band: ≥3,000 m.
How to read the range figure
Compare the stated target and visibility condition, not the headline metre count. If a datasheet and this page disagree, the datasheet governs the order.
