PLRF-R138-B1.2 Long Range Laser Rangefinder Module
Introduction
The PLRF-R138-B1.2 Long Range Laser Rangefinder Module is developed based on the 1570 nm solid-state laser independently researched and developed by Lumispot. Advanced algorithms are integrated for long-distance ranging, adopting pulse time-of-flight ranging technology. The product features fully domestic sourcing, high cost-performance, high reliability and high shock resistance.
