Overview
The Lumispot ELRF-F21 is a laser rangefinder module (LRF module) built around a 1535 nm erbium laser and a single-pulse Time-of-Flight (TOF) method. It delivers a maximum ranging distance of >=6 km with measurement accuracy of <=+/-1 m. The module features compact dimensions, low power consumption, RS422/TTL communication interfaces, and Class 1 (<1 mW) eye safety, suitable for integration into handheld, vehicle-mounted, and pod-based electro-optical equipment.
