Through the ingenious optical path design of this kit, users can simply switch the light source (e.g., from a broadband LED white light to a monochromatic 532 nm laser module) or replace the object to be imaged (such as magnetic reticles, apertures, or resolution test targets) to flexibly conduct various geometric aberration experiments in a single demonstration system. Examples include observing the focal spot of spherical aberration, demonstrating the "comet tail" phenomenon of coma, distinguishing the tangential and sagittal line foci of astigmatism, as well as correcting pincushion distortion and chromatic aberration's colored halos. This highly integrated approach not only facilitates instructors in combining Gaussian optics theory with the actual causes of aberrations to achieve lively and interactive classroom teaching but also enables students to engage in hands-on operation, develop experimental skills, and deepen their intuitive understanding of core concepts such as spherical aberration, coma, astigmatism, field curvature, distortion, and positional/magnification chromatic aberration. This effectively bridges the gap between theoretical knowledge and practical application, enhancing the overall effectiveness of optical education.
