Plan PLMi S50x/0.70 — Infinity‑corrected brightfield objective for materials‑science bScope systems (Euromex)

The Plan PLMi S50x/0.70 is an infinity‑corrected 50x objective optimised for brightfield inspection of metallographic and materials samples, offering a short working distance for close observation without cover‑glass correction

• Infinity‑corrected optical design
• High numerical aperture 0.70 for detail resolution
• 3.7 mm working distance for sample access
• Designed for materials‑science brightfield use

Achieve finer detail with a high‑aperture plan objective

The combination of a Plan correction and an NA 0.70 delivers improved flatness across the field and increased resolution, enabling clearer observation of microstructures such as grain boundaries, phases and surface defects. An objective with a high numerical aperture collects more light and resolves smaller features; this translates into more reliable visual analysis and fewer repeat inspections. The 50x power is commonly used in metallography and material‑science quality control to reveal features not visible at lower magnifications while keeping a practical working distance for metallographic samples.

Short working distance tailored for materials handling

A 3.7 mm working distance provides sufficient clearance for removal of polishing residues removal, micro‑probing or focused illumination arrangements while maintaining high optical performance. Because this objective is supplied without cover‑glass correction, it is especially suitable for direct inspection of polished sections, cross‑sections and other bulk samples rather than sealed slide preparations. The absence of cover‑glass compensation simplifies setup for standard materials workflows and avoids the need to adjust for varying cover‑glass thicknesses, reducing setup time and measurement variability.

Reliable integration and consistent image results in bScope stations

Designed for the bScope series, the Euromex objective offers an infinity‑corrected optical path that matches modern microscope tube systems and imaging accessories, enhancing compatibility with additional intermediate optics or camera adapters. This design choice supports consistent image reproduction and easier calibration across different inspection stations, which helps maintain traceable inspection routines. The robust plan objective also supports reproducible brightfield contrast, aiding documentation and comparison during failure analysis or routine quality control. SKU BS.8150 identifies this specific configuration for procurement and inventory.

FAQ

What types of samples is this objective intended for?
This objective is intended for materials‑science and metallographic samples; the Plan PLMi S50x/0.70 performs well on polished sections, cross‑sections and bulk materials in brightfield inspection.

Does the objective require a cover glass for correct imaging?
No, the objective is supplied without cover‑glass correction, so the Plan PLMi S50x/0.70 is suitable for direct inspection of unmounted samples and polished specimens.

Is the objective limited to Euromex microscopes?
The lens is designed for the bScope series and the infinity‑corrected optical path supports standard infinity tube length systems; compatibility should be confirmed for third‑party microscope systems before integration.

How does a numerical aperture of 0.70 affect image quality?
An NA 0.70 increases resolving power and light collection, improving the visibility of fine microstructural detail and contrast in brightfield images, which supports more accurate inspections.

What practical advantage does a 3.7 mm working distance provide?
A 3.7 mm working distance gives room for sample handling, lighting adjustments and small tooling operations while maintaining optical performance, facilitating efficient inspection workflows.
