What is a LRF Laser Range Finder and what is its purpose?

LRF or a Laser Range Finder is a device used to measure distances. Most laser rangefinders operate on the time-of-flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Some Higher end Laser Rangefinders can achieve millimeter level precision. Even over long distances.

Laser rangefinders use advanced technology developed for the military to accurately measure the distance to a target. LRFs work by pulsing a SWIR laser 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.

Infiniti uses weapons-grade LRFs that are produced for a variety of applications such as weapons targeting, advanced tracking, autonomous cars, and surveillance. Our EDPSS erbium-glass diode-pumped solid-state SWIR micro lasers provide short, high-pulse-energy pulses, with diffraction-limited beam quality and low divergence, resulting in superior range and performance.
