10mm Plan Stress-Free PLPORLi 10x/0.25 IOS Objective for iScope Reflected and Transmitted Polarisation, No Cover Glass Correction - Euromex

Take advantage of a combination of 10× magnification, a numerical aperture of 0.25 and a 10 mm working distance to achieve repeatable polarised inspections in mixed transmitted and reflected-light workflows; order the lens directly via Metav Werkzeuge or consult our specialists for integration advice.

IS.7910-R objective lens (10×, NA 0.25, 10 mm working distance)

The IS.7910-R is an objective for the iScope series, engineered for polarised reflected and transmitted-light inspection with plan, stress-free optics and a fixed 10 mm working distance.

• 10× plan objective, stress-free design
• Numerical aperture 0.25 for clear resolution
• 10 mm working distance for sample clearance
• Polarisation-capable for contrast enhancement

High-resolution optics for consistent inspection results

The lens delivers 10× magnification combined with a numerical aperture of 0.25, providing a balance between depth of field and resolving power that favours practical inspection tasks. The plan, stress-free optical design reduces image distortion across the field, so features remain well defined from edge to centre. These characteristics contribute to stable measurement and documentation routines, supporting higher first-pass acceptance rates in production control and quality assurance.

Why numerical aperture and working distance matter

The numerical aperture 0.25 determines the objective’s light-gathering capacity and resolving limit; higher NA improves detail capture but narrows depth of field. In parallel, the 10 mm working distance offers sufficient clearance for uneven specimens and fixturing without compromising image quality. For technicians less familiar with optical terms: a modest NA with a generous working distance often provides the best compromise between ease of use and fine-detail detection in industrial inspection settings.

Suitable uses and optical behaviour in polarised setups

Designed for both reflected and transmitted-light polarisation, the lens supports contrast enhancement techniques used in material inspection and microstructure analysis. Because the design specifies no cover-glass correction, the optical path is optimised for specimens viewed without a cover slip; this is advantageous for bulk samples, metallographic mounts and layered assemblies where a cover glass would alter focus. Integration into polarised workflows helps reveal stress patterns, birefringence and subtle surface features that standard brightfield observation can miss.

System integration and practical handling

The objective is part of the iScope series and complements modular microscope configurations where polarisation capability is required. The plan, stress-free construction simplifies alignment and reduces the need for frequent recalibration under normal use, supporting predictable results across shifts. For documentation and repeated inspections, consistent optical geometry streamlines imaging parameters and reduces operator-dependent variation, thereby improving traceability in inspection records.

FAQ

Is this objective suitable for polarised microscopy?
Yes. The IS.7910-R objective is specified for polarisation in both reflected and transmitted-light setups, enabling contrast enhancement and stress or birefringence visualisation.

What does "no cover-glass correction" mean for routine inspection?
It means the IS.7910-R is optimised for specimens viewed without a cover glass; for samples requiring a cover slip, optical aberrations can occur unless compensated by other system optics.

Can the objective be used for metallographic inspection?
Yes. The plan, stress-free design and 10 mm working distance make the lens appropriate for metallographic mounts and bulk specimens commonly encountered in industrial microscopy.

How does the numerical aperture affect image quality in practice?
The numerical aperture of 0.25 offers improved detail resolution while maintaining a practical depth of field, which is beneficial for routine inspection where both clarity and handling tolerance are important.

Is the lens compatible with all iScope models?
The objective is part of the iScope series and is intended for iScope-compatible mounts; compatibility depends on the microscope’s mechanical interface and polarisation module configuration.
