Delphi‑X Observer DX.7200 — 100x oil‑immersion microscope objective by Euromex

Delphi‑X Observer DX.7200 is a 100x oil‑immersion microscope objective engineered for high‑resolution life‑science and metrological imaging, offering a short working distance for maximised numerical aperture performance.

• 100x high‑power magnification
• Numerical aperture 1.25 for resolution
• 0.2 mm working distance
• Oil immersion PLi design

Exceptional image resolution for critical measurement tasks

The combination of 100x magnification and a numerical aperture of 1.25 delivers substantially increased resolving power and light collection compared with lower‑NA lenses. In practice, a higher NA improves detail visibility and contrast when inspecting fine structure or performing dimensional checks under a microscope. The optical design is optimised for high‑resolution imaging, so individual features can be distinguished more reliably, which supports reproducible measurement workflows in both research and industrial inspection.

Practical benefits of oil immersion and short working distance

This immersion lens uses oil immersion to minimise refractive losses between the cover slip and the objective, translating into better image uniformity and higher effective resolution at high magnifications. The working distance of 0.2 mm is intentionally short to allow the lens to achieve its peak optical performance; this results in sharper images but requires cautious handling and stable specimen mounting. For users unfamiliar with immersion techniques, the benefit is a noticeably crisper image and improved signal when examining submicrometre structures or surface finishes.

Integration into laboratory and metrology setups

Designed as part of the Delphi‑X Observer series, the lens supports precision imaging tasks where optical performance is paramount. The oil‑immersion construction makes it particularly suitable for life‑science microscopy and metrology applications that demand the finest detail. When incorporated into a calibrated microscopy workflow, this objective contributes to consistent observation and measurement results, reducing uncertainty in visual inspection and analytical routines.

FAQ

What immersion medium is required for this objective?
The Euromex Delphi‑X Observer DX.7200 is specified as an oil immersion objective and must be used with appropriate immersion oil to achieve the stated numerical aperture and image quality.

How does a numerical aperture of 1.25 affect imaging?
A numerical aperture of 1.25 increases light‑gathering ability and resolving power, allowing finer detail to be observed; the DX.7200 therefore yields higher contrast and resolution than lower‑NA objectives at equivalent magnification.

Is the short working distance of 0.2 mm problematic for fragile samples?
The working distance of 0.2 mm requires careful specimen preparation and stable focusing to avoid contact; for delicate samples, secure mounting and cautious focusing procedures are recommended when using the DX.7200.

Which applications benefit most from this lens?
This immersion objective is optimised for life‑science microscopy and metrology tasks where submicrometre detail and reproducible imaging are essential; it is well suited to high‑resolution inspection and measurement workflows.

How should the objective be cleaned after use with immersion oil?
After use, remove excess oil with lens tissue and a small amount of appropriate cleaning fluid recommended for microscope optics; follow established laboratory procedures to protect coatings and preserve the DX.7200’s performance.
