Item is in excellent cosmetic and optic condition.
The Leitz Wetzlar Apo 40/0.95 (170 / 0.11–0.23) is a highly regarded classic 
high-dry objective from the era of mechanical 170 mm tube-length Leitz microscopes 
(such as the Ortholux, Orthoplan, and Dialux).
Apo: Apochromatic Correction: Corrected for chromatic aberration across three wavelengths (red, green, blue) and spherical aberration for two colors. It provides high color fidelity, minimal color fringing, and high contrast.
40x: Magnification: 40x power.
0.95: Numerical Aperture (NA): Extremely high for a "dry" (non-immersion) lens. NA 0.95 approaches the physical limit of light gathering in air (~1.0), giving this lens exceptionally high resolving power.
170: Mechanical Tube Length: Designed for 170 mm mechanical tube length stands (classic Leitz standard prior to the shift to 160 mm and later infinity systems).
0.11–0.23: Correction Collar Range: Variable cover-slip thickness correction range in millimeters.
Plezy: Phase Contrast / Special Variant: "Plezy" (or related Leitz phase/contrast designations like PV/Plezy) indicates built-in elements for specific illumination modes—most commonly phase contrast or specialized contrast methods.
