High-Precision LRF (Laser Range Finder) with 31km Extended Range

Our laser range finders use advanced technology developed for the military to accurately measure the distance to a target. LRFs work by pulsing laser light in the SWIR wavelengths towards a target. A receiver then detects the reflection of that light and accurately calculates the distance based on the time it took for the light to bounce back.

This weapons-grade LRF provides an accuracy as good as 1–50cm, with an extended range up to 31km in ideal conditions. The 1550nm solid state SWIR micro laser provides short, high-pulse energy pulses, with diffraction-limited beam quality and low divergence, resulting in superior range and performance.

LRFs are used in a host of applications such as weapon targeting, advanced tracking, autonomous cars and geo locking surveillance. Our LRFs utilize low-noise, high-efficiency photoreceivers that have been designed and optimized for ranging. The customized electronics are designed to improve accuracy performance while reducing false reflections and echoes.

Infiniti uses high quality weapons-grade LRFs, however they still suffer from problems and limitations common to the technology that affect all LRFs. For more info, please see our LRF Whitepaper on Ranging Performance.
