Microscope objective Delphi‑X Observer DX.7320 — 20x, NA 0.50 (Euromex)

The Microscope objective Delphi‑X Observer DX.7320 is a 20x objective intended for life‑science microscopy, delivering strong light collection and close‑in sample access for detailed observation.

• 20x magnification for detailed observation
• Numerical aperture 0.50 for improved resolution
• Working distance 2.1 mm for close sample access

Better image detail through optical performance

The optical specification centres on a numerical aperture of NA 0.50, paired with 20x magnification, which together increase the lens system's ability to resolve fine structure and to collect light efficiently. In practical terms, a higher numerical aperture means improved resolution and better contrast for weakly stained or low‑contrast preparations. The stated optical values are taken from the manufacturer documentation and offer a verifiable basis for selecting an objective when precision imaging and reproducible results are required in routine laboratory environments.

Compact working distance for life‑science samples

A working distance of 2.1 mm enables close approach to thin specimens and coverslip‑mounted samples, making the objective suitable for detailed examinations where instrument geometry demands compact clearance. The PL‑SAFi optical designation, as referenced in the manufacturer PDF, indicates an optical configuration intended to reduce field curvature and to support consistent image flatness across the field of view. This configuration benefits common laboratory workflows by reducing the need for repeated refocusing during tiled or extended examinations while maintaining high image fidelity.

Integration and practical notes for laboratory use

Specified for use with standard microscope setups, the Euromex Delphi‑X Observer series item DX.7320 integrates the described optical performance into routine microscopy tasks. The microscope objective is listed under accessories for microscopes and is intended for life‑science applications as referenced in the source documentation. For handling, routine optical care is advised: dust removal with appropriate lens tissue and cleaning solutions designed for optical coatings. The combination of 20x, NA 0.50 and 2.1 mm working distance yields a balance between magnification, light collection and sample accessibility that supports reproducible imaging in many analytical and observational laboratory scenarios.

FAQ

What is the numerical aperture and why does it matter?
The numerical aperture NA 0.50 determines light‑gathering power and resolution; the Euromex Delphi‑X Observer DX.7320 uses this aperture to improve detail and contrast in typical life‑science imaging.

Is this objective suitable for coverslip‑mounted samples?
Yes; the 2.1 mm working distance of the DX.7320 is compatible with many coverslip‑mounted preparations, allowing close approach while maintaining the stated optical performance.

Which microscopes is the objective compatible with?
The item is listed under accessories for microscopes and is designed to integrate into standard objective mounts; specific mechanical compatibility should be verified against the microscope's nosepiece specifications prior to purchase for the Euromex DX.7320.

How should the lens be maintained to preserve image quality?
Cleaning with approved lens tissue and optical cleaning fluid is recommended; avoid abrasive materials and excessive mechanical contact to maintain the coating and optical surfaces of the DX.7320.

Where do the technical specifications come from?
Manufacturer documentation (Life Science PDF) provides the specifications for the Delphi‑X Observer series; the listed values for 20x, NA 0.50 and working distance 2.1 mm are quoted from that source.
