iScope IS.7440 — microscope objective, 40x, NA 0.75 (Euromex)

The iScope IS.7440 microscope objective is a high‑magnification optical unit designed for life‑science microscopy and precision imaging tasks, delivering 40x power with a numerical aperture of 0.75 and a working distance of 0.34 mm.

• 40x magnification
• Numerical aperture 0.75
• Working distance 0.34 mm

Exceptional resolution for detailed imaging

The combination of 40x magnification and a numerical aperture (NA) of 0.75 provides a clear advantage where fine structural detail must be resolved. A higher NA increases the light‑gathering capacity of the lens, which directly improves resolution and contrast under brightfield and other transmitted‑light techniques. In practical terms, this optical specification enables sharper images of cellular structures and thin specimen details, reducing the need for excessive digital enhancement and helping to deliver reproducible, measurable results for documentation and analysis.

Close working distance explained and its practical benefits

A working distance of 0.34 mm means the focal point lies very close to the front lens element. Working distance denotes the gap between the objective tip and the specimen at focus; a short distance favours high‑numerical‑aperture designs and supports improved resolving power. This specification suits thin samples, cover‑slip preparations and high‑resolution inspections where minimal optical path distortion is critical. Note that such a short working distance requires careful sample preparation and handling to avoid contact, but rewards users with superior detail and fidelity in microscopic observation.

Designed for seamless integration into microscopy setups

Belonging to the iScope series, this objective is specified as S40x/0.75 PLFi in technical documentation and is intended for direct integration with standard microscope nosepieces that accept comparable objective threads and mounting standards. The optical unit’s geometry and performance characteristics make it appropriate for life‑science benches, educational labs that demand advanced detail, and routine imaging tasks in quality control. Compatibility should be confirmed against the local microscope model; the SKU IS.7440 provides an exact reference for ordering and matching components.

Built for consistent performance and dependable workflows

High‑precision optics are as much about repeatability as they are about peak performance. The lens design and listed specifications support consistent imaging across sessions, which is essential for longitudinal studies, comparative analysis and quality assurance protocols. Combined with Metav’s role as a “quality filter” for the European market, choosing components with clearly stated optical data helps reduce procurement uncertainty and supports predictable laboratory workflows. For further technical clarifications, the original Life Science PDF lists the S40x/0.75 PLFi specification and can be referenced for confirming exact optical parameters.

FAQ

What level of magnification does this objective provide? The objective offers 40x magnification, delivering detailed enlargement suitable for cellular and thin‑section observation.

How does the numerical aperture affect image quality? A numerical aperture of 0.75 increases light collection and resolution; the higher NA improves contrast and fine detail visibility in transmitted‑light techniques.

Is the working distance sufficient for routine samples? The working distance of 0.34 mm is short, which is ideal for high‑resolution inspections of thin samples and cover‑slip preparations but requires careful sample handling to prevent contact.

Which product reference should be used when ordering or checking compatibility? Use the SKU IS.7440 and the article number IS.7440 as exact references when ordering or verifying compatibility with microscope tube and nosepiece standards.

For which applications is this optical unit most suitable? This objective is specified for life‑science microscopy and precision imaging tasks where high resolution and superior detail reproduction are priorities.
