Break through the aberration bottleneck of "thick glass + high magnification", clearly present the deep structure of thick substrates (such as multi-layer circuit crossing areas) in the near-ultraviolet range, and be compatible with laser processing.

Applications include:
Depth defect analysis of large-sized thick glass panels (automotive/medical screens) (such as circuit short circuits under 1.1mm glass);
Near-ultraviolet spectral research on liquid crystal materials (apochromatism ensures the accuracy of multi-wavelength data).
