The MDA Space’s Laser Range Finder (LRF) altimeter provides time-critical range measurements to a host spacecraft to support deep space landing applications such as to asteroids, comets or planets.

Consisting of an Integrated Optics Assembly, an Integrated Electronics Assembly and housing, MDA Space's LRF uses Time-of-Flight (TOF) technology to perform rapid and accurate range measurements from 1m to max range, depending on target reflectivity, and has the ability to extract receive signals from extremely low reflectance targets.
