With a compact 24x16x20.4mm form factor, low average power consumption, and a ranging capability beyond 5m under specified low-turbidity conditions, this underwater LiDAR supports mapping, positioning, and navigation for pool-cleaning and other underwater robots. \u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan style=\"color: #ff9c00;\"\u003eNote:\u003c\/span\u003e\u003c\/b\u003e This TF-UW500 underwater LiDAR does not include a back cover and has no waterproof protection rating.

The dToF ranging system combines a narrow 0.5° field of view with a Class 1 laser, providing a small optical spot, strong directionality, and a wide usable incidence angle. This optical ranging approach also helps minimize multipath interference compared with traditional ultrasonic sensing.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E39027-content2.webp?v=1791666625\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCentimeter-Level Accuracy for Mapping and Positioning\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThis underwater LiDAR provides accuracy of \u0026lt; 3cm and repeatability of \u0026lt; 1cm @ 1σ across the 0.1 ~ 2m range, together with 1mm distance resolution.
