Plan PLMi 5x/0.12 IOS objective — Euromex microscope objective with 5× magnification and 15.5 mm working distance

The Plan PLMi 5x/0.12 IOS objective is an infinity-corrected microscope objective engineered for flat-field imaging where a moderate magnification and an extended working distance are required

• Plan-corrected optics for flat images
• 5× magnification, NA 0.12
• Infinity-corrected optical design
• Working distance 15.5 mm, no cover-glass correction

Improved image uniformity for inspections and documentation

This objective delivers a noticeably flatter image field compared with standard lenses, which reduces edge curvature and eases image stitching and measurement tasks. The Plan-corrected optics ensure that detail remains sharp across the field of view, a practical advantage for routine inspections, sample documentation and teaching demonstrations. The moderate 5× power balances resolution and field of view, so features are easier to locate and measure without frequent stage adjustments. The design supports efficient workflows by lowering the need for post-capture correction and by improving the reliability of visual comparison and image analysis.

Practical optical design and what the specifications mean

The lens is infinity-corrected, which means it was designed to work in microscopes that use an infinity optical path; this enables use of additional optical modules or tube lenses without changing the focal characteristics. The numerical aperture of 0.12 determines resolving power and depth of field — here it offers a compromise between contrast and working distance, giving a useful depth of focus for thicker specimens. The label indicates no cover-glass correction, so the objective is optimised for use without a cover slip or with specimens where cover-glass correction is unnecessary; this avoids spherical aberration caused by incorrect cover-glass compensation and simplifies use with mounts or holders that preclude a cover slip.

Where this objective adds value in the lab or classroom

The combination of 15.5 mm working distance and flat-field correction makes the lens well suited to applications such as quality control inspections, biological teaching labs and material surface observation where ease of handling and operator safety are important. The extended working distance creates more space for manipulators, micro-tools or probe heads while keeping the specimen in focus. As a component of the IOS series, the lens integrates readily into common educational and industrial microscope stands, providing reproducible imaging for routine checks or demonstration purposes. If the application is specialised or the optical path unusual, technical advice is available to confirm compatibility and expected performance; enquiries may be addressed by e‑mail or telephone to discuss requirements.

FAQ

What does "no cover-glass correction" mean for everyday use?
No cover-glass correction means the Euromex IS.8105 objective is optimised for specimens without a cover slip or where cover-glass thickness is not applied; this reduces spherical aberration when a cover slip is absent.

Which microscope types are compatible with this objective?
The lens is infinity-corrected, so the IS.8105 fits microscopes that use an infinity optical path and a compatible tube lens; compatibility checks should be made against the microscope manufacturer's specifications.

Is the 15.5 mm working distance suitable for sample manipulation?
Yes — the 15.5 mm working distance provides comfortable space for micro-manipulation or inspection with probes while maintaining focus and image quality with this objective.

Can this objective be used for documentation and image stitching?
The plan-corrected design of the IS.8105 provides a flat field that reduces distortion at the edges, supporting accurate documentation and seamless image stitching for reproducible results.
