Delphi‑X Observer DX.7300 microscope objective — 100x, NA 1.40 (Euromex)

Delphi‑X Observer DX.7300 is an oil‑immersion microscope objective engineered for high‑magnification, high‑resolution imaging in demanding microscopy applications

• 100x magnification for detailed imaging
• High numerical aperture 1.40 for better resolution
• Very short working distance 0.18 mm requiring immersion oil
• PL‑SAFi oil immersion design for increased contrast

Resolve finer detail with high numerical aperture optics

The combination of 100x magnification and a numerical aperture of 1.40 prioritises optical resolving power and light collection. A higher numerical aperture reduces the diffraction limit and increases image contrast, which is essential when distinguishing closely spaced structures. The oil immersion configuration minimises refraction at the interface between specimen and objective, providing sharper detail than a dry lens at equivalent magnification. This paragraph explains why the optical numbers matter rather than only listing them, enabling informed decisions for laboratory equipment planning.

Practical implications for laboratory workflows

A working distance of 0.18 mm implies close proximity between the cover slip and the objective front element; this is typical for high‑NA 100x oil objectives and allows for maximal numerical aperture usage. Users should expect to apply an appropriate immersion medium and take normal precautions during handling to avoid contact with delicate optics. The lens is intended for microscopy tasks where enhanced resolution is required, such as cellular imaging and detailed surface inspections. For procurement, Metav Werkzeuge offers product availability checks and can assist with compatibility questions for existing microscope stands.

Handling, integration and what to expect in practice

The PL‑SAFi oil immersion specification indicates that the objective is optimised for oil between the cover slip and the lens to deliver its rated performance. The short working distance brings a requirement for precise focusing and stable specimen mounting; this leads to reproducible results when combined with correct sample preparation. The objective is manufactured by Euromex and identified as DX.7300 in technical documentation; consult the referenced Life Science PDF for the original specification text. Clear preparatory steps and correct immersion technique yield the promised improvement in image quality and measurement confidence.
