Plan PLMi 10x/0.25 — Infinity-corrected objective for bScope materials science

The Plan PLMi 10x/0.25 objective is a specialist optical component designed for materials science inspection on bScope microscopes, optimised for both bright-field and dark-field observation.

• Plan-corrected optics for flat field images
• 10× magnification for efficient overview
• Numerical aperture 0.25 for fine resolution
• 9.3 mm working distance for sample clearance

High-resolution imaging for reproducible results

The Plan-corrected design produces a flat imaging field, reducing edge curvature and ensuring consistent sharpness across the field of view. With 10× magnification combined with a numerical aperture of 0.25, the objective balances depth of field and resolving power to make fine structural details visible without sacrificing ease of use. The optical quality supports repeatable measurements and reliable documentation in laboratory and production environments, making the component suitable for routine failure analysis and material characterisation.

Adaptable contrast modes for materials inspection

Engineered for both bright-field and dark-field techniques, the lens enables flexible contrast strategies for surface and subsurface features. The compatibility with common oblique illumination methods enhances the visibility of scratches, inclusions and microstructures that are otherwise difficult to detect. The 9.3 mm working distance 9.3 mm provides ample clearance for larger specimens or fixturing, while preserving the optical distance required for sharp, high-contrast imaging in industrial inspection workflows.

Designed for reliable integration into inspection systems

The infinity-corrected optical concept allows the objective to be used with tube lenses and imaging systems that rely on an infinity image plane, simplifying optical system design and alignment. As a Plan PLMi unit, the lens is specified without cover glass correction, which is advantageous when inspecting bare materials or metallographic preparations where no cover slip is applied. The solid optical construction and precise mechanical interfaces support stable mounting and minimal drift for extended inspection sessions.

Workshop-ready performance and procurement confidence

For purchasing and operational planning, the optical component offers clear, measurable benefits: infinity-corrected optics for system compatibility, Plan correction for field flatness and a 9.3 mm working distance for handling convenience. Metav’s proposition of democratised precision means availability, traceability and reliable delivery from a central European quality hub. For additional technical specifications or to confirm system compatibility, Metav’s consultancy is available and can supply the necessary documentation to integrate the objective into production or laboratory equipment.

FAQ

Is this objective compatible with bScope microscopes? The Plan PLMi 10x/0.25 objective (SKU BS.8810) is specified for the bScope materials science series and is suitable where an infinity-corrected, Plan objective is required.

Can this lens be used with samples under a cover glass? The objective is supplied without cover glass correction, so optical performance is optimised for specimens without a cover slip; using a cover glass may alter focus and introduce aberrations.

What does the 9.3 mm working distance mean for inspection tasks? A 9.3 mm working distance provides clearance for fixturing and manipulation of samples while maintaining the necessary optical distance for sharp imaging, useful in metallography and component inspection.

Does the infinity-corrected design require a specific tube lens? Yes — as an infinity-corrected objective, the lens requires a matching tube lens or imaging system configured for an infinity image plane to achieve the specified performance.

What image quality can be expected from a 10× / NA 0.25 objective? The combination of 10× magnification and numerical aperture 0.25 delivers a balance of field of view and resolution that reveals surface structure and fine details while providing sufficient depth of field for practical inspection work.
