Microscope objective Delphi‑X Observer DX.7304 — Euromex 4×, NA 0.13, 16.5 mm WD

The Microscope objective Delphi‑X Observer DX.7304 is a 4× microscope objective designed for routine observation and overview imaging in life science and quality-control applications.

• 4× magnification for overview imaging
• 16.5 mm working distance for sample clearance
• Numerical aperture 0.13 for bright-field contrast

Fast, reliable overview imaging with controlled resolution

The 4× magnification of this objective offers a large field of view that speeds up sample scanning and reduces the number of objective changes during routine inspections. With a numerical aperture of 0.13, the lens balances resolution and depth of field, delivering clear bright-field contrast while maintaining easier focus across uneven samples. The specified working distance of 16.5 mm provides practical clearance for manipulations or larger specimen holders, so inspections and preparatory steps can be performed without constant repositioning of the sample.

Optical designation and what it means for everyday use

Specified as a 4×/0.13 PL‑SAFi objective in the Life Science PDF, this designation indicates a design optimised for flat-field imaging and consistent performance across the field of view. The optical correction reduces edge distortion and improves image uniformity, which is useful when documenting specimens or when using digital cameras for documentation. For laboratories and workshops that value reproducible results, the combination of a corrected field and moderate numerical aperture reduces retakes and saves time during routine workflows.

FAQ

What imaging tasks is this objective best suited for?
The Microscope objective Delphi‑X Observer DX.7304 (Euromex, DX.7304) is primarily intended for overview imaging, rapid sample inspection and applications where a wide field of view and practical working distance are required.

How does the numerical aperture affect image quality with this objective?
With a numerical aperture of 0.13, the DX.7304 provides a balance between contrast and depth of field, giving clearer bright-field images for uneven samples while keeping focus tolerance larger than high‑NA objectives.

Is the working distance sufficient for manipulations or larger sample holders?
The specified working distance of 16.5 mm for the DX.7304 allows additional clearance for manipulation and sample mounting, reducing the need for frequent repositioning during routine tasks.

Where can further technical documentation for this objective be found?
Technical specifications for the Delphi‑X Observer DX.7304 are referenced in the Life Science PDF; consult the document for the PL‑SAFi designation and exact optical parameters.
