Plan stress-free PLPOLi 5x/0.12 IOS objective for iScope (IS.7905-T) — 5×, 15.5 mm working distance — Euromex

The Plan stress-free PLPOLi 5x/0.12 IOS objective is optimised for transmitted-light polarisation inspections on iScope microscopes, offering a 15.5 mm working distance and operation without cover-glass correction

• Plan stress-free optical correction
• 5× magnification for low-power overview
• Numerical aperture 0.12 for good depth of field
• 15.5 mm working distance, no cover-glass correction

Flat-field optics for true-to-sample imaging and reliable polarisation results

The objective combines plan correction with a stress-free optical design, which keeps the imaging field flat and minimises internal birefringence. For quality control and material inspection this means fewer artefacts and truer colour contrast when working with polarised transmitted light. The PLPOLi designation indicates polarisation-optimised performance, so samples examined under crossed polarising filters show reliable extinction and interference colours. For technicians and laboratory engineers unfamiliar with these terms: a flat field reduces the need for refocusing across the image and a stress-free lens prevents unwanted internal stresses from affecting polarisation readings.

Low-power overview and practical handling during sample work

With 5× magnification and a numerical aperture of 0.12, the lens provides a wide field of view and good depth of field for rapid inspection and orientation steps. This configuration is ideal for scanning larger areas before switching to higher-power objectives, reducing inspection time and improving throughput. The 15.5 mm working distance gives clear space for sample manipulation, polariser inserts or thicker specimens, and the absence of cover-glass correction means the lens is suited to samples examined without a cover slip or when precise cover-glass control is not required. Integration into iScope transmitted-light polarisation setups is straightforward, accelerating routine checks and production-line sampling.

Practical benefits for integration, workflow and repeatability

This objective is designed for straightforward mounting in compatible optical systems and contributes to repeatable measurements thanks to its optical stability. The compatibility with an IOS optical system ensures consistent image projection into the microscope tube or camera path without unexpected vignetting. For process engineers, the main benefits are predictable polarisation behaviour, reduced inspection variability and easier sample handling. If additional technical data are required to confirm fitment with a specific iScope model or camera, technical advice is available from Metav Werkzeuge; pairing the right objective with existing microscope elements helps maintain inspection accuracy and shortens setup time.
