SF23/B LiDAR sensor Datasheet 1. Overview The SF23/B is a very low power LiDAR that can be used in energy critical applications where batteries or solar cells are used. It is a small form factor, general purpose LiDAR sensor that measures the distance to objects by timing a laser flash. Accuracy is not generally affected by the colour or texture of the target surface, nor the angle of incidence of the laser beam. The SF23/B is tolerant to changes in background lighting conditions, wind and noise.

SF23/B LiDAR sensor Datasheet 3. Quickstart guide Caution The SF23/B laser rangefinder contains a laser and should never be aimed at a person or an animal. Do not look at the beam directly with optical instruments. ● ● ● ● ● ● ● Download the L ightWare Studio application to your PC or laptop. Instal and start the application by following the prompts. Connect the SF23/B to the PC using a serial to USB adaptor. The SF23/B will automatically be detected by the application.

SF23/B LiDAR sensor Datasheet 4. Safety instructions The SF23/B emits ionizing laser radiation. The level of the laser emission is Class 1 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. Caution The use of optical instruments with this product will increase eye hazard.

It can be mounted with a vertical or horizontal lens orientation. Several mounting accessories can be purchased or downloaded from the L ightWare website. Do not mount the rangefinder within the cavity of an airframe, rather mount it directly at the surface boundary.
