Delphi‑X Observer DX.7340 microscope objective by Euromex — 40x, NA 0.75

The Delphi‑X Observer DX.7340 is a 40x microscope objective tailored for life‑science and laboratory imaging, delivering a high numerical aperture for enhanced detail and contrast in close‑focus applications.

• 40x magnification for detailed observation
• High numerical aperture 0.75 for superior resolution
• 0.7 mm working distance for close focusing
• Designed for Delphi‑X Observer series by Euromex

Improved image detail where it matters most

The combination of 40x magnification and a numerical aperture of 0.75 provides a tangible benefit for routine and precise inspection tasks: finer structural detail and improved light collection. The numerical aperture describes the objective’s ability to gather light and resolve fine features; a higher value increases resolving power and depth of field in high‑magnification imaging. For laboratories requiring consistent optical performance, this objective delivers high resolution while maintaining reliable contrast, helping to reveal subcellular structures and subtle sample features that lower‑NA optics can miss.

Compact working distance for dense setups and fine‑detail work

With a 0.7 mm working distance, this objective is optimised for applications that need close proximity between lens and specimen, such as high‑detail surface inspection or tightly constrained sample holders. Working distance is the physical gap between the front lens and the specimen at focus; a short distance enables higher numerical apertures and thus better resolution, though it requires attention to sample preparation and stage clearance. For compact microscopes and systems with limited headroom, the objective’s geometry supports integration without compromising optical throughput or image quality.

Consistent optical specification and series compatibility

The objective is specified as S40x/0.75 PL‑SAFi in source documentation, reflecting its optical design and intended performance class. Manufactured by Euromex for the Delphi‑X Observer range, the lens is aligned to industry expectations for laboratory objectives in this magnification band. The documented parameters (magnification, working distance, numerical aperture) allow straightforward comparison with alternative optics and support predictable imaging outcomes — a practical advantage when standardising instruments across a workshop or research facility.

Practical integration advice and application scope

This microscope objective suits life‑science imaging and microscopy workflows that prioritise resolution over long working distance, such as detailed cell imaging or inspection of small components. When integrating the lens, ensure stage and condenser configurations accommodate the short 0.7 mm working distance and verify mechanical mounting matches the host microscope’s objective turret. If additional technical data or compatibility checks are needed, specification support is available to confirm fit and optical alignment before procurement.

FAQ

What magnification does the objective provide?
The objective provides 40x magnification, suitable for high‑detail laboratory imaging with the Delphi‑X Observer series.

What is the numerical aperture and why does it matter?
The numerical aperture is 0.75; a higher numerical aperture increases light collection and resolving power, so the DX.7340 delivers improved detail and contrast compared with lower‑NA lenses.

How close can the lens focus to the sample?
The working distance is 0.7 mm, which enables higher resolution but requires sufficient stage clearance and careful sample preparation when using the DX.7340 objective.

Is this objective compatible with standard microscope turrets?
The DX.7340 is designed for the Delphi‑X Observer series and similar microscope configurations; verify turret thread and mounting specifications if integration with another system is planned.

Where do the specification values originate?
Key values such as magnification, working distance and numerical aperture are specified in source documentation (Life Science PDF) for the S40x/0.75 PL‑SAFi class, as referenced for the DX.7340.
