Lightware SF20 LIDAR Laser Rangefinder

The LW20 and SF20 miniature laser rangefinders offer high performance in a very small form factor. The LW20 is a sealed unit designed to withstand water splashes and dust while the SF20 is a lightweight, open frame unit ideal for OEM integration. Both units can measure up to 50m or 100m in sunlit conditions and can measure down to almost zero distance. These professional grade sensors take up to 678 readings per second and provide distances to both the first and last signals with each measurement.

The laser beam is encoded so that units can be aimed at the same target without interfering with each other, enabling multiple redundancy and allowing for many UAVs to operate safely in the same area. Serial or I2C communications ports provide a comprehensive suite of commands and the unit can be switched into power saving mode when not in use.

By adding a small digital servo such as the Corona DS-919MG, the SF20 can be turned into a tiny scanning LiDAR capable of capturing 360 points per second while scanning the area ahead of an autonomous vehicle. Ideal for sense-and-avoid and navigation, the SF20 can either stream the measured data or make decisions based on preset alarms. 

Laser safety is an important issue to all users of laser rangefinders. Please take note of the warning information shown in the manuals and on the stickers that go with every LRF. All LightWare rangefinder products are Class 1M or Class 1, eye safe.
