A 360° lens, commonly used in industrial borescopes, is a non-destructive inspection device designed for comprehensive internal examination. Its core component is a lens capable of capturing panoramic images across a full 360 degrees. With specialized optical design and image acquisition technology, the lens can obtain all-around imaging of the inspection area in a single view, eliminating the need for repeated adjustments as required in traditional endoscopes. These systems typically include a probe lens, transmission cable, image processing unit, and display terminal. They are extensively used in aerospace, automotive, power, and petrochemical industries for inspecting internal features such as pipes, cavities, and engine components, helping engineers detect cracks, wear, foreign object residues, and other internal defects.
