Achios‑X Observer AX.7300 — 100x oil‑immersion microscope objective (Euromex)

The Achios‑X Observer AX.7300 is an oil‑immersion microscope objective optimised for high‑resolution life science applications, offering an extremely high numerical aperture and a short working distance suitable for standard coverslip preparations.

• 100x oil-immersion magnification
• Numerical aperture 1.40 for high resolution
• Working distance 0.18 mm for close focusing
• Designed for life science microscopy applications

Exceptional resolving power for detailed imaging

With a numerical aperture (NA) of 1.40, this objective gathers a large cone of light, which directly improves resolution and image contrast when combined with immersion oil. The 100x specification is paired with oil immersion to reduce refractive index differences between the specimen and the lens, enabling clearer visualisation of fine structures. For laboratories requiring clear sub‑cellular detail, the combination of high NA and oil‑immersion translates into measurable gains in image fidelity and diagnostic confidence.

Close working distance that supports delicate sample interrogation

The short working distance of 0.18 mm allows the front lens element to sit close to the specimen plane, which is essential for achieving the designed optical performance at high magnifications. This proximity facilitates high‑numerical‑aperture imaging on specimens mounted beneath coverslips and is particularly beneficial for thin, high‑contrast preparations. Handling and focusing demand careful technique, but the result is sharper optical sectioning and improved light throughput for demanding microscopy tasks.

Optimised for life science workflows and reproducible results

Built for microscopy in research and clinical environments, the objective is specified for oil‑immersion use and aligns with standard life science mounting media and coverslip thicknesses. The optical combination supports applications such as brightfield and differential contrast where high NA is advantageous. Clear labelling and technical data make the objective straightforward to integrate into existing optical trains, and the documented specifications support reproducible imaging protocols across instruments and teams.

FAQ

Is the Achios‑X Observer AX.7300 suitable for oil‑immersion use?
Yes. The Achios‑X Observer AX.7300 is an oil‑immersion microscope objective specified for use with immersion oil, delivering the stated performance at the quoted working distance.

What does a numerical aperture of 1.40 mean for imaging?
A 1.40 numerical aperture indicates a high light‑gathering ability and improved resolving power; the Achios‑X Observer AX.7300 therefore provides enhanced resolution and contrast compared with lower‑NA objectives.

Can the short working distance be used with standard coverslips?
The 0.18 mm working distance is intended for specimens prepared under coverslips; appropriate mounting and careful focusing are required to avoid contact while achieving optimal image quality with the Achios‑X Observer AX.7300.

Which applications are recommended for this objective?
This objective is optimised for life science microscopy where high magnification and superior resolution are needed, for example cellular and sub‑cellular imaging, as indicated by the product specifications.

What identifier should be used when ordering or documenting this objective?
Refer to the article number and SKU AX.7300 and the model series Achios‑X Observer (Manufacturer: Euromex) for procurement and lab records.
