MarkingMeaning & Technical Specification
Leitz
WetzlarManufacturer: Ernst Leitz Wetzlar, West Germany.
NPLNormal Plan: Flat-field correction designed for field
numbers up to roughly 22
mm. It ensures the image remains sharp across the majority of the field of
view without edge curvature.
FLUOTARSemi-Apochromatic / Fluorite Optics: Constructed with synthetic fluorite
glass ()
elements. This delivers superior color correction (chromatic aberration
reduction) and significantly higher contrast/brightness compared to standard
achromats.
6.3Magnification:
.0.20 Numerical Aperture (NA): 0.20,
which provides good light-gathering capability and resolving power for a
low-power scanning objective.
Pol (or P)Polarization /
Strain-Free: Optics and lens housings are specifically selected and mounted
without mechanical stress or internal birefringence. Crucial for petrographic,
geological, material science, or polarized light applications.
170Mechanical Tube Length: Designed for classic 170 mm finite optical
tube systems.
/-Coverglass Thickness: Independent (no coverglass required). At , coverglass thickness
variations ( to )
have a negligible effect on image quality.
