05 Nov 2024 Powell lenses are optical marking prisms that allow laser beams to pass through and be optimally drawn into a straight line with uniform optical density, good stability, and good linearity, which can eliminate the central hot spot and fading edge distribution of Gaussian beams, which is suitable for various biomedical, automotive assembly, food processing and other machine vision applications.
