LightWare SF45/B 50m Scanning LiDAR Range Sensor

Price

$449.00

SENSE AND AVOID: The world’s smallest and lightest scanning LiDAR sensor. The LightWare SF45 gives "eyes" to high-cost unmanned autonomous vehicles (UAVs) and machines, lowering the risk of catastrophe and the safe delivery of payloads.

The horizontal field of view can be adjusted from a few degrees up to 320 degrees to suit the application.

Objects up to 50 meters away can be detected and avoided by finding clear pathways using simple navigation commands.

The SF45/B is tolerant to changes in background lighting conditions, wind, and noise.

Overview

The SF45/B is a small, lightweight scanning lidar ideal for obstacle detection by small autonomous vehicles. The horizontal field of view can be adjusted from a few degrees up to 320 degrees to suit the application. Objects up to 50m away can be detected and avoided by finding clear pathways using simple navigation commands. The SF45/B is tolerant to changes in background lighting conditions, wind and noise.

The following capabilities are included in the SF45/B as standard:

Streaming of live readings.
Alarms when an obstacle is detected.
Configurable update rate and scanning angle.
Internal status monitoring.

Safety instructions

The SF45/B emits ionizing laser radiation. The level of the laser emission is Class 1M which indicates that the laser beam is safe to look at with the unaided eye but must not be viewed using binoculars or other optical devices. Notwithstanding the safety rating, avoid looking into the beam and switch the unit off when working in the area.

The SF45/B should not be disassembled or modified in any way. The laser eye safety rating depends on the mechanical integrity of the optics and electronics so if these are damaged do not continue using the SF45/B. There are no user serviceable parts and maintenance or repair must only be carried out by the manufacturer or a qualified service agent. No regular maintenance is required for the SF45/B but if the lenses start to collect dust then they may be wiped with suitable lens cleaning materials.

The Acroname Support Engineering Team can help you decide if the LightWare SF45/B is right for your needs and systems. Support is also available for setup and troubleshooting. Call or email our US-based support team.
