Cylindrical lens/Large Optics
- Cylinder lenses, as the ones with a different type of X-axis and Y-axis radius, have cylindrical or semi-cylindrical shape and enlarging images are available only on a single axis.
- Flat products can be processed up to the line PV λ/10 in case of thickness ≤30T and line PV λ/4≥50T.
