Microscope objective 86.556 — Euromex 40x, NA 0.85

The Microscope objective 86.556 is a 40x objective designed for high‑resolution microscopy applications, offering a large numerical aperture and a short working distance suitable for detailed sample observation

• 40x magnification for detailed imaging
• High numerical aperture 0.85 for improved resolution
• Short 0.6 mm working distance for close-focus samples

High numerical aperture for clearer, higher‑contrast images

A numerical aperture of 0.85 noticeably increases the objective's ability to gather light and resolve fine detail, which is critical when analysing cellular structures or fine surface features. In practical terms, the elevated NA translates into sharper images and better contrast under moderate illumination, helping to reduce exposure time and improve throughput in repetitive inspection tasks. For laboratories seeking reliable optical performance, this characteristic supports consistent results across routine and advanced examinations.

Forty‑times magnification tailored for life‑science observations

With a 40x magnification, the objective provides the balance between field of view and detail that many biological and materials investigations require. This level of enlargement is well suited to studies where subcellular features or microstructural details must be inspected without switching frequently between objectives. The optical design preserves image flatness and clarity across the central field, enabling efficient documentation and measurement workflows with standard microscope camera systems.

Short working distance: benefits and practical considerations

The 0.6 mm working distance indicates that the lens focuses very close to the specimen plane, which offers advantages when working with thin preparations or coverslipped slides where high‑resolution contact is needed. At the same time, the small separation necessitates careful sample handling and precise stage control to avoid collisions. For applications requiring mechanical probes or thicker specimens, assess compatibility with sample holders and consider whether a longer‑WD objective is required; for thin sections and high‑detail inspection, the compact focus depth is a practical asset.

FAQ

What does the numerical aperture 0.85 mean for image quality?
A higher numerical aperture, as in the Euromex 86.556 objective, increases the lens's light‑gathering power and resolving capability, resulting in finer detail and improved contrast under comparable illumination.

How does the 0.6 mm working distance affect sample handling?
The 0.6 mm working distance of this objective requires precise stage control and careful specimen preparation, since the lens focuses very close to the cover slip or specimen surface.

Is this objective suitable for routine life‑science applications?
Yes, the 40x magnification combined with a high numerical aperture makes the lens well suited to many routine life‑science inspections where detailed cellular or microstructural observation is required.

Can standard microscope cameras be used with this objective?
Standard camera systems designed for transmitted or reflected light microscopy are commonly compatible; check camera sensor size and tube optics to ensure the desired field of view and resolution when paired with this objective.

Where can detailed technical specifications be verified?
Detailed optical data and official specifications are available in the manufacturer's documentation; the listed values in product literature include magnification 40x, NA 0.85 and WD 0.6 mm
