High-Frequency 905nm Laser Rangefinder Modules

905nm High-Frequency Laser Rangefinder Modules

The ERDI High-Frequency Series represents a new generation of industrial laser rangefinders designed specifically for high-speed dynamic measurement applications. Unlike traditional modules that only update a few times per second, our high-frequency modules can deliver up to 10,000 distance measurements per second, making them ideal for capturing fast-moving objects and micro-changes in industrial environments.
