Plan PLMi S50×/0.70 — Microscope objective with infinite correction for materials science (Euromex bScope)

A Plan PLMi S50×/0.70 microscope objective engineered for materials science inspection, offering brightfield and darkfield capability with no cover-glass correction and a compact 2.5 mm working distance.

• High 50× magnification
• Numerical aperture 0.70 for resolution
• 2.5 mm working distance for tight setups
• Infinite-corrected optics for modern microscopes

Precision imaging for materials science inspection

The Plan PLMi S50×/0.70 objective combines a plan optical design with an infinite-corrected tube-length concept to ensure flat field performance across metallographic samples. This results in consistently sharp images across the field, which is essential when documenting microstructures or performing comparative measurements. The combination of 50× magnification and NA 0.70 supports fine feature detection while maintaining contrast for etched surfaces. In practice, this means fewer retakes and more reliable visual evidence in quality-control workflows.

What the optical specifications deliver in practice

A higher numerical aperture (NA 0.70) increases light-gathering power and lateral resolution, enabling clearer delineation of grain boundaries, inclusions and surface finish details under brightfield conditions. The 2.5 mm working distance is deliberately short to permit compact illumination geometries and efficient darkfield coupling; users benefit from improved contrast when inspecting surface defects. The infinite-corrected design decouples the objective from the tube lens, simplifying system upgrades and ensuring compatibility with a range of modern microscope stands and camera adapters.

Integration and system compatibility

Designed as a component for microscope systems, the objective is well suited to bScope configurations and other industrial stands that accept infinite optics. The infinite correction allows straightforward integration with tube lenses and camera cassettes while preserving field flatness. The objective is specified for brightfield and darkfield techniques and does not include cover-glass correction, which makes it particularly appropriate for direct-surface inspection and metallographic samples rather than routine biological slides. For questions about mechanical mounting or to confirm optical compatibility, Metav Werkzeuge can provide tailored guidance.

Handling, maintenance and operational benefits

Built for routine laboratory and workshop use, the objective’s plan correction reduces the need for repeated focusing and compensating adjustment, which speeds up inspection cycles. The absence of cover-glass correction simplifies setup when working with unmounted specimens or polished sections. Regular cleaning with appropriate optical cloths and lens fluid preserves performance; because optics are precision components, careful handling reduces downtime and maintains measurement confidence.

FAQ

What magnification and resolution can be expected from this objective?
The Plan PLMi S50×/0.70 objective (Euromex, SKU BS.8850) delivers high-detail imaging at 50× magnification with a numerical aperture of 0.70, suitable for resolving fine microstructural features in metallographic samples.

Is this objective suitable for standard biological slides with a cover glass?
This objective is specified without cover-glass correction, so it is optimised for direct-surface inspection and polished sections rather than routine biological slides that require cover-glass compensation.

Can the objective be used for both brightfield and darkfield techniques?
Yes — the optics are designed for compatibility with both brightfield and darkfield illumination, enabling flexible contrast methods for surface and defect visualisation.

Will this objective fit existing microscope systems?
The infinite-corrected design makes the objective compatible with microscopes that accept infinite optics and a suitable tube lens; confirm mechanical fit and parfocal settings with Metav Werkzeuge before installation.

How should the optics be cleaned and maintained?
Clean only with designated optical cleaning cloths and lens fluid; handle the Plan PLMi S50×/0.70 carefully to avoid contact with the front element and store in protective caps when not in use.
