Plan stress-free PLPOLi 20x/0.40 IOS objective (iScope, polarisation) — Euromex

The Plan stress-free PLPOLi 20x/0.40 IOS objective is a transmitted-light polarisation objective for iScope systems, corrected for a 0.17 mm cover glass and specified for a 5.1 mm working distance

• Plan stress-free optics for accurate polarisation
• 20x magnification with 0.40 numerical aperture
• Corrected for 0.17 mm cover glass

Consistent polarised images for reliable analysis

The objective delivers flat-field (plan) performance so structures across the entire field stay in focus, which is essential for inspection and documentation tasks. The stress-free optical design reduces internal birefringence that can distort polarised light, ensuring that polarimetric contrast reflects the specimen rather than the lens. For laboratories and quality departments this means fewer repeat scans and more dependable image-based decisions, improving throughput and traceability.

Faster workflows through defined working distance and optics

With a 5.1 mm working distance and 20x magnification, the lens balances resolution and sample clearance for routine transmitted-light polarisation applications. The specified working distance supports the use of thicker specimens or modest illumination accessories without risking contact. Together with the 0.40 numerical aperture, the objective enables sharper detail capture while keeping depth of field manageable for inspection tasks, so measurement and documentation proceed with less handling time.

What plan and stress-free mean in practice

A plan objective corrects field curvature so that the centre and edges of the image are equally sharp; this is particularly useful when stitching images or comparing regions across a slide. The term stress-free indicates that the glass and mounting minimise internal stress-induced birefringence, which is critical when working with polarised light—otherwise false anisotropy can appear. These optical qualities translate into clearer micrographs and more reliable material analysis, even for users with basic polarisation experience.

Engineered for iScope transmitted-light polarisation systems

Designed for iScope transmitted-light polarisation setups, the objective is corrected for a 0.17 mm cover glass, matching standard slide preparations to avoid spherical aberration. Compatibility with the iScope range simplifies integration and reduces the need for additional correction collars or adapters. The optical specification supports documentation, routine failure analysis and educational polarisation demonstrations where reproducible image quality is required.

Practical benefits for inspection and documentation teams

Specimen handling is simplified by predictable imaging behaviour: fewer focus adjustments, consistent contrast in polarisation, and reduced artefacts. That promotes a smoother inspection routine and lowers the risk of misinterpretation during quality control. For procurement and workshop managers the combination of robust optical design and industry-standard corrections contributes to a dependable imaging chain from sample to report.

FAQ

Is this objective compatible with all iScope transmitted-light polarisation stands?
The objective is specified for iScope transmitted-light polarisation systems and was designed to match their optical path; compatibility checks with the exact stand model are recommended.

What does "stress-free" mean for polarisation work?
Stress-free indicates minimal internal glass stress and mounting strain, reducing lens-induced birefringence so polarisation contrast represents the specimen rather than the optics.

Can the objective be used without a cover glass?
The objective is corrected for a 0.17 mm cover glass; using no cover glass may introduce spherical aberration or a focus shift compared with standard slide preparations.

How does the 5.1 mm working distance affect sample handling?
A 5.1 mm working distance provides moderate clearance for sample manipulation and illumination accessories while maintaining the optical performance required for high-contrast polarisation imaging.

Is the objective suitable for documentation and image stitching?
Yes — the plan correction provides a flat field that supports stitching and consistent documentation across the image field.
