Achios‑X Observer AX.7240 microscope objective — 40x magnification, NA 0.65, short working distance (Euromex)

The Achios‑X Observer AX.7240 microscope objective is a 40x lens designed for applications requiring high detail and strong light collection in close‑proximity observations

• 40x magnification for detailed observation
• Numerical aperture 0.65 for improved resolution
• Working distance 1.5 mm for close specimen access

High-resolution imaging enabled by strong optical aperture

With a 40x magnification combined with a numerical aperture (NA) of 0.65, this objective delivers improved resolving power and better light‑gathering compared with lower‑NA lenses. A higher numerical aperture increases the amount of light that reaches the image plane, which results in clearer contrast and finer detail in the focal plane. This benefit is particularly relevant for inspections where distinguishing small structural features is essential; the optical specification therefore supports efficient image acquisition and more reliable visual analysis.

Short working distance for thin specimens and high‑detail inspection

The 1.5 mm working distance is a defining characteristic of this design and suits tasks that require close optical access to a specimen, for example thin sections, coverslip preparations and fine surface inspection. A reduced working distance contributes to a compact optical path and helps maintain high numerical aperture performance at elevated magnifications. Operators should account for the proximity when planning sample mounting and objective switching, since the near field favours delicate or precisely positioned specimens rather than bulky samples.

Practical compatibility and application orientation

As a member of the Achios‑X series, the objective is engineered for microscope setups where high resolution and compact optics are priorities. The lens is intended for optical microscopes requiring standard objective integration; selection of the correct tube lens and system parfocality will preserve the stated optical performance. Reference data for system integration is provided in the original Life Science documentation and should be consulted when precise optical parameters or compatibility with specialised stands are required.

Handling and care to retain optical performance

Maintaining the condition of the front element and preserving the alignment of the optical assembly extends service life and conserves image quality. Regular inspection, dust protection when not in use and gentle cleaning with approved optical solvents and lens tissue will prevent contamination and scratches. Proper handling during mounting and avoiding contact with the front lens element will sustain the numerical aperture and preserve the 40x performance for routine microscopy tasks.

FAQ

What magnification does this objective provide?
The Achios‑X Observer AX.7240 provides a 40x magnification, specified for detailed specimen observation.

What does numerical aperture 0.65 mean in practice?
A numerical aperture of 0.65 indicates a relatively high light‑gathering capacity for this magnification, improving resolution and contrast in the focal plane for the AX.7240 objective.

Which specimen types are best suited to the short working distance?
Specimens such as thin sections and coverslip‑mounted preparations benefit from the 1.5 mm working distance of the AX.7240, where close optical access enhances detail capture.

How should the objective be cleaned and stored?
Cleaning should be performed with appropriate optical cleaning fluid and lens tissue; the objective must be stored in a dust‑free environment and protected by caps to preserve optical performance.

Is the objective part of a series that supports system matching?
Yes, the lens belongs to the Achios‑X Observer series, designed for applications where high resolution in a compact optical package is required; consult system documentation for exact matching parameters.
