Plan PLMi 10x/0.30 Brightfield/Darkfield IOS Objective — Objective / lens by Euromex, 11 mm working distance, M26 mount

The Plan PLMi 10x/0.30 Brightfield/Darkfield IOS Objective is an objective lens designed for routine inspection and documentation where a long working distance and stable focus changeover are required

• Plan-corrected optics for flat field
• 10× magnification with 0.30 NA
• 11 mm long working distance
• 45 mm parfocal, M26 thread

High-precision imaging for consistent inspection results

The objective delivers 10× magnification combined with a 0.30 numerical aperture, enabling a balance between depth of field and resolution that is suited to industrial inspection and routine microscopy. The Plan-corrected optics reduce field curvature, so images remain sharp across the field—this brings measurable time savings in quality control, as fewer refocusing steps are needed during visual checks or when capturing images for documentation. The optical specification supports clear detail reproduction, which is essential when assessing component features or solder joints under brightfield or darkfield illumination.

Long working distance that protects samples and tooling

With an 11 mm working distance, the lens allows safe manipulation of components beneath the objective, making it suitable for assemblies, loose parts inspection and situations where probes or tweezers must operate without risk of contact. The extended clearance reduces the chance of accidental collisions and simplifies handling of thicker specimens or fixtures. Because the objective is specified without cover-glass correction, it is best used with uncovered samples or setups where a cover slip is not present; this detail should be considered when integrating the lens into a bench microscope or inspection station.

Parfocal design and M26 mounting for efficient system workflows

A 45 mm parfocal distance means that focus is retained when switching between objectives designed to this standard, speeding up multi-magnification workflows and reducing downtime. The M26 thread provides straightforward mechanical compatibility with many industrial microscope turrets and camera adapters, easing retrofits and replacements. These mechanical standards support modularity in the optical chain, allowing the lens to be combined with cameras, illuminators and stands without extensive custom adaptation.

Practical applications and integration advice

The objective is optimised for both brightfield and darkfield observation modes, offering contrast versatility for matte, reflective or low-relief surfaces. In assembly inspection, electronics testing and material surface analysis, the combination of magnification, aperture and working distance produces actionable images for defect detection and measurement tasks. When specifying an optical train, ensure that the rest of the system—camera sensor size, tube lens and illumination—matches the objective's IOS characteristics to preserve image quality and field coverage.

FAQ

What magnification and resolving power does this objective offer?
The objective provides 10× magnification with a 0.30 numerical aperture, which offers a compromise between resolution and depth of field suitable for many industrial inspection tasks.

Is the lens suitable for use with cover slips and thin-mounted samples?
This objective is supplied without cover-glass correction, so it is intended for uncovered specimens or setups where no cover slip is present; for cover-glass work, an objective with correction collar should be chosen.

How does the 11 mm working distance benefit production inspection?
An 11 mm working distance allows safe handling and the use of probes or tools under the lens, reducing the risk of contact and facilitating inspection of thicker parts or fixtured assemblies.

Can this objective be swapped with other lenses without significant refocusing?
Yes, the 45 mm parfocal design keeps focus consistent when changing between objectives that conform to the same parfocal standard, helping to maintain throughput in multi-magnification inspections.

What mount and mechanical compatibility should be expected?
The objective uses an M26 thread, compatible with many industrial turret systems and camera adapters; confirm mechanical adapters for specific microscope models before installation.
