50x Plan Stress-Free PLPOLRi Objective 0.75 NA 0.92mm Working Distance, Polarising - Euromex

Take advantage of the combination of high-resolution polarising optics, a short 0.92 mm working distance, and 0.75 numerical aperture for confident material analysis; order the objective directly via Metav Werkzeuge or consult our specialists if guidance is required.

iScope PLPOLRi 50x/0.75 Plan strain-free polarising objective (Euromex)

An iScope PLPOLRi 50x/0.75 objective engineered for polarisation inspection in both reflected and transmitted light, without cover-glass correction

• Plan, strain-free polarising optics
• 50× high magnification for detailed inspection
• Numerical aperture 0.75 for improved resolution
• 0.92 mm working distance for close sample work

Accurate polarisation contrast for reliable material assessment

The plan, strain-free design delivers uniform field flatness and reduces optical artefacts that can otherwise complicate polarisation analysis. With emphasis on consistent image quality, this objective supports precise observations of crystalline structures, stress patterns and anisotropic materials. The corrected field reduces the need for frequent focal adjustments, which translates into faster inspection cycles and fewer re-measurements for production or laboratory workflows.

Fine structure resolution thanks to high magnification and aperture

Equipped with 50× magnification and a numerical aperture of 0.75, the lens raises the resolving power of the microscope system, enabling detection of fine birefringent features and microstructural detail. Higher NA increases light-gathering ability and contrast under polarised illumination, so small differences in retardation or extinction angles become more apparent. The result is clearer micrographs and more reliable assessments during metallography, mineralogy or materials research.

Optimised for reflected and transmitted polarised light workflows

Designed for both reflected (episcopic) and transmitted (diascopic) polarisation work, this objective integrates smoothly into iScope systems and similar optical setups. The absence of cover-glass correction means the lens is best applied to direct sample examination or when cover-glass compensation is handled elsewhere in the optical chain. The short 0.92 mm working distance favours high-magnification inspection of prepared specimens, thin sections and polished surfaces where proximity to the sample improves contrast and detail.

Consistent results for production and laboratory environments

The mechanical and optical design focuses on repeatability and low-maintenance operation, supporting continuous use in inspection stations and research benches. Its polarising capability and planar correction reduce the need for corrective post-processing, accelerating throughput and decision making. For workshops seeking dependable optics without compromising on measurement fidelity, the objective contributes to a smoother quality-assurance routine and fewer sample re-runs.

FAQ

Is this objective compatible with iScope microscopes?
Yes. The objective is specified for the iScope series and is supplied as the Euromex PLPOLRi 50x/0.75 objective (SKU IS.7950-R), designed to integrate with standard iScope optical mounts.

Can the lens be used for both reflected and transmitted polarisation work?
Yes. The optical design supports polarised light inspection in both episcopic (reflected) and diascopic (transmitted) modes for flexible laboratory or production use.

What does 'no cover-glass correction' mean in practice?
It indicates the objective does not compensate for cover-glass thickness; the lens performs optimally when samples are presented without a cover glass or when correction is applied elsewhere in the optical path.

How does a numerical aperture of 0.75 affect image quality?
A higher numerical aperture improves resolution and light collection, yielding better contrast under polarised illumination and enabling clearer visualisation of fine microstructural features.

Which sample types benefit most from this objective?
Materials with birefringence, polished metallographic specimens, thin sections and anisotropic minerals benefit from the polarising capability and high resolving power of this lens.
