Leica x63 Plan Apo
These are rare objectives in the used market. PL APO objectives – the class for professionals. They deliver imaging quality that cannot be achieved by conventional objectives. Plan Apochromats provide perfect axial and lateral color matching for applications requiring fast color change and the colocalization of structures. PL APO objectives are characterized by flawless image flatness up to a field number of 25. Top numerical apertures define a resolving power at the limits of what is physically possible. Within the class of apochromats, Leica offers PL APO lenses especially designed to match the highest specifications for confocal scanning (CS). This is one of those objectives – x63 oil immersion offered here at a fraction of the list price. The objective screw thread is the standard Leica M25x0.75 mm (non RMS).
