Products carry the ERDI LASER brand. The catalog prioritizes 905 nm laser rangefinder modules and also includes a separately identified 940 nm sensor, 1535 nm / 1.54 um-family rangefinder modules and erbium-glass pulsed laser sources. A laser source is an emitter component rather than a complete rangefinder; use each exact model record for wavelength and specifications. ## Procurement guides and company facts - 1535 nm Eye-Safe Laser Rangefinder Modules for UAV Payloads: https://erdilrf.com/1535nm-laser-rangefinder-module-for-drones/ - 905 nm UART Laser Rangefinder Modules for OEM Integration: https://erdilrf.com/905nm-uart-laser-rangefinder-module-oem/ - OEM / ODM Laser Rangefinder Module Procurement in China: https://erdilrf.com/oem-odm-laser-rangefinder-module-china/ - 905 nm vs 1535 nm Laser Rangefinder Modules: https://erdilrf.com/905nm-vs-1535nm-laser-rangefinder-module/ - Laser Rangefinder Module vs LiDAR for UAV Integration: https://erdilrf.com/laser-rangefinder-module-vs-lidar-for-uav/ - ERDILRF Company and Product Catalog Facts: https://erdilrf.com/facts/ ## Product families - LR series: https://erdilrf.com/models/lr-series/ - SPD series: https://erdilrf.com/models/spd-series/ - H series: https://erdilrf.com/models/h-series/ - VB series: https://erdilrf.com/models/vb-series/ - LRF A series: https://erdilrf.com/models/a-series/ - 1535 nm rangefinders: https://erdilrf.com/models/c-series/ - Erbium-glass laser sources: https://erdilrf.com/models/laser-series/ ## Guides - Laser rangefinder module selection guide: https://erdilrf.com/laser-rangefinder-module/ - Manufacturer and OEM/ODM information: https://erdilrf.com/laser-rangefinder-module-manufacturer-china/ - UAV and gimbal payload modules: https://erdilrf.com/uav-gimbal-laser-rangefinder-module/ - Integrator resources (wiring, protocols, drivers): https://erdilrf.com/integrators/ - 905 nm vs 1535 nm wavelength guide: https://erdilrf.com/knowledge/905nm-vs-1535nm-choosing-wavelength/ ## Comparison and integration guides - dToF vs triangulation: choosing a distance sensor: https://erdilrf.com/knowledge/dtof-vs-triangulation-distance-sensor/ - IP67 vs IP65 for laser distance sensors: https://erdilrf.com/knowledge/ip67-vs-ip65-laser-distance-sensor/ - Laser rangefinder module price: published tiers: https://erdilrf.com/knowledge/laser-rangefinder-module-price/ - ERDI vs LightWare: OEM rangefinder comparison: https://erdilrf.com/knowledge/erdi-vs-lightware-rangefinder/ - ERDI vs TeraRanger: long-range vs short-range ToF: https://erdilrf.com/knowledge/erdi-vs-teraranger-distance-sensor/ - ERDI vs Benewake: matching the sensor to the task: https://erdilrf.com/knowledge/erdi-vs-benewake-lidar/ - Lidar-Lite alternatives for OEM integration: https://erdilrf.com/knowledge/lidar-lite-alternative-oem/ - Raspberry Pi UART: reading an ERDI rangefinder: https://erdilrf.com/knowledge/raspberry-pi-laser-rangefinder-uart/ - PX4 rangefinder integration: three routes: https://erdilrf.com/knowledge/px4-laser-rangefinder-integration/ - Beam divergence and spot size for rangefinders: https://erdilrf.com/knowledge/rangefinder-beam-divergence-spot-size/ ## Open source and citable records - Drivers (Python, Arduino, ROS 2; MIT licence): https://github.com/ErdiTech/erdi-lrf-drivers - Technical note, DOI 10.5281/zenodo.23297197: https://doi.org/10.5281/zenodo.23297197 - Driver software archive v0.1.0, DOI 10.5281/zenodo.23297253: https://doi.org/10.5281/zenodo.23297253 Model matches use product group and published range.
