Industries that require precise distance measurements in varying conditions often rely on Laser rangefinder (LRF) modules. These are compact, integrated systems use laser technology to determine the distance to a target by calculating the time it takes for a laser pulse to travel to the object and back. As their use have grown in automation, robotics, smart surveillance, and environmental monitoring industries, the demand for eye-safe lasers has increased significantly. Industrial demands for LRF modulenow also include accuracy and safety in sensitive operational environments.
Laser rangefinder module
An LRF module, or laser rangefinder module, is the primary functional component of a laser distance-measuring system. Unlike handheld laser rangefinders, LRF modules are designed to be integrated into larger systems, like drones and UAVs, autonomous vehicles, industrial robotics, military targeting systems, environmental monitoring equipment, and smart traffic control systems.
The primary components of these modules include: a laser emitter, a photodetector (to capture the reflected signal), timing circuitry, and processing units for calculation and communication.
With the evolution of laser technology, modern LRF modules now deliver non-contact, highly accurate distance readings, even in challenging environments.
Eye safe lasers in industrial applications
Laser technology, while efficient, poses potential risks to human vision. When misused or unshielded, laser beams, especially in invisible wavelengths, are known to cause temporary or permanent retinal damage.
That’s why eye-safe LRF modules, often classified under Class 1 laser safety standards, are increasingly becoming the standard in industrial settings.
Industries prefer eye-safe lasers for various reasons:
Compliance with safety standards
Many industries operate under strict safety regulations governed by applicable standards, where using eye-safe modules are essential to ensure compliance.
Safe Integration in public or shared environments
When integrated in different equipment, eye-safe lasers ensure safety and unrestricted deployment.
ERDI TECH LTD, a leading laser design and development firm, offers LRF module, and various other laser products with eye-safe feature.
