Leitz PL Fluotar 50x metallurgical objective
$355.00
Leitz (marked �Leitz Wetzlar Germany�) microscope objective for metallurgical instruments, of Plan Fluotar correction. �Plan� objectives are corrected to display a perfectly flat image of up to 28mm in diameter, while Fluotar objectives represent a very high degree of color correction..
� Magnification: 50x
� Numerical Aperture: 0.85na
� Infinity corrected
� Thread size RMS
� Must be used WITHOUT cover glass
� Spring-loaded sample / objective protection:
� Leica catalog number: 567 013
The standard RMS objective thread allows this objective to be used on earlier metallurgical instruments manufactured by Leitz from as long ago as the 1950’s, and via a ‘step-up’ 32mm thread adapter, on most of the currently produced instruments from Leica Microsystems.
The objective is in near-perfect condition, and the glass is flawless.

Leitz PL Fluotar 50x/0.85 Metallurgical Microscope Objective (Finite 160mm Tube Length)
This is a premium Leitz PL Fluotar 50x metallurgical objective, designed for high-resolution imaging of opaque samples in reflected light. With a numerical aperture (NA) of 0.85, it delivers exceptional brightness, contrast, and detail for demanding applications in metallurgy, materials science, semiconductor inspection, and epifluorescence. Compatible with Leitz microscopes using a 160mm finite tube length and RMS thread.
Key Specifications:
-
Magnification: 50x
-
Numerical Aperture (NA): 0.85 (high resolution and light-gathering power)
-
Optical Design: PL Fluotar – Plan-corrected for a flat field, Fluorite-grade glass for high transmission and low autofluorescence
-
Mechanical Tube Length: Finite 160mm (for Leitz/Leica DM R, Metalloplan, Orthoplan, etc.)
-
Thread: RMS (Royal Microscopical Society standard)
-
Working Distance: Typically short (exact distance varies; standard for high-NA metallurgical objectives)
-
Correction: Corrected for no cover glass (0.17mm cover glass not used in reflected light)
-
Application: Reflected light brightfield, darkfield, DIC, polarization, and epifluorescence
Why This Objective Is a Premium Choice:
-
Fluotar Optics: Superior to standard achromats, offering better color correction, higher transmission (ideal for fluorescence), and excellent field flatness.
-
High NA (0.85): Provides excellent resolution for detailed imaging of grain structures, inclusions, and micro-features.
-
Leitz Legacy: Part of the renowned Leitz/Leica quality lineage, sought after for research and industrial inspection.
Applications:
-
Metallurgical Sample Analysis: Grain structure, phase identification, failure analysis.
-
Materials Science: Imaging ceramics, composites, polished geological samples.
-
Semiconductor/PCB Inspection: Defect review, layer alignment, micro-circuit analysis.
-
Fluorescence Microscopy: Suitable for blue/green fluorophores due to high transmission and low autofluorescence.
