Delphi‑X Observer DX.7740 — 40x microscope objective, high NA 0.65 (Euromex)

The Delphi‑X Observer DX.7740 is a microscope objective optimised for life‑science imaging, offering a high‑aperture plan design suited to detailed sample observation in research and industrial laboratories

• High NA 0.65 for improved resolution
• Short working distance 0.7 mm for close focus
• Compatible with Delphi‑X Observer series

Precision optics for reliable high‑resolution imaging

The optical design centres on a numerical aperture engineered to maximise light collection and contrast, which directly improves image sharpness and resolving power. A high‑aperture plan objective corrects field curvature, producing a flat image plane across the field of view; this reduces the need for frequent refocusing and supports reproducible documentation of microstructures. By prioritising optical performance, the objective enables shorter exposure times and better signal‑to‑noise ratios, helping laboratories to increase throughput without compromising data quality.

Close working distance for controlled surface inspection

A working distance of 0.7 mm allows close access to specimen surfaces, making the objective particularly suitable for fine detail inspection and manipulation under the microscope. Close working distance demands careful handling and appropriate sample preparation, but it also permits use of immersion media or fine‑scale measurements where depth resolution is critical. The compact clearance benefits applications that require simultaneous imaging and micro‑instrument interaction, such as microdissection or probe‑based metrology, while the optical design maintains contrast despite the reduced separation from the sample.

Smooth integration into life‑science imaging workflows

Designed for laboratory environments, this plan objective combines high aperture and a machining‑grade finish to support routine research and industrial microscopy. The design supports consistent imaging across sessions and complements modular microscope systems within the Delphi‑X Observer series.

FAQ

What imaging improvements does a high numerical aperture provide?
A high numerical aperture increases light collection and resolving power; the DX.7740’s NA 0.65 delivers finer detail and better contrast for high‑resolution microscopy tasks.

Is this objective suitable for delicate biological samples?
Yes, the plan‑type optical correction and high aperture make the objective appropriate for many life‑science applications, though the 0.7 mm working distance requires careful sample handling.

Which microscopes is this objective compatible with?
The objective is designed for integration within the Delphi‑X Observer series and other microscopes that accept standard objective mounts and dimensions associated with this product class.

Are there special handling considerations for the short working distance?
Because the working distance is compact, close sample approach is required; this benefits surface‑sensitive tasks but necessitates careful lens and specimen handling to avoid collision.
