LRF20

High-Precision LRF (Laser Range Finder) with 20km Extended Range

20km Extended Range Laser Rangefinder

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 20–250cm, with an extended range up to 20km in ideal conditions. The 1530nm 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.
