Microscope Objective 86.554 — 20x, NA 0.65 (Euromex)

Microscope Objective 86.554 is a high-resolution 20x objective intended for life-science microscopy and close-sample inspection, offering a compact working distance and elevated light-gathering ability.

• 20x magnification for detailed observation
• Numerical aperture 0.65 for high resolution
• Working distance 1.5 mm for close focusing

Sharper detail through higher numerical aperture

The Microscope Objective 86.554 combines 20x magnification with a numerical aperture (NA) of 0.65, which increases the system's resolving power and improves light collection. In practical terms, a higher NA means finer structural detail becomes visible and contrast is enhanced under transmitted light. This optical specification supports more reliable identification of small features in stained preparations and thin sections, helping to reduce rework from unclear images and accelerating routine inspections.

Close working distance for precise surface inspection

A working distance of 1.5 mm enables focused observation of surfaces and thin specimens where proximity to the sample benefits image resolution. The short physical clearance improves optical performance but requires careful sample mounting and handling to avoid contact with the lens. Where necessary, adapt sample holders or use thinner cover slips to maintain safety while taking advantage of the objective's improved image quality and contrast.

Fit for life-science workflows and straightforward integration

The objective follows the PLFi designation noted in the product documentation and is intended for standard microscope objective turrets used in laboratory environments. Its optical characteristics make it suitable for high-detail bright-field and contrast-enhanced observation in educational, research and routine laboratory settings. For mechanical and optical interoperability, confirm turret size and parfocal requirements with existing equipment; technical documentation from Euromex clarifies mounting dimensions and optical data.

FAQ

What level of detail can be expected with this objective?
The Euromex microscope objective 86.554 provides 20x magnification and an NA of 0.65, offering improved resolving power and contrast for detailed observation of thin specimens and stained preparations.

What does the 1.5 mm working distance mean in practice?
A working distance of 1.5 mm indicates the physical clearance between the front lens element and the specimen at focus; it enables close-up imaging but requires careful sample handling and appropriate holders to avoid contact.

Which microscopes is the objective compatible with?
This objective is designed for standard microscope objective turrets used in life-science laboratories; check the turret thread and parfocal height against existing equipment before fitting the Euromex objective.

How should the lens be cleaned and maintained?
Cleaning the optical surfaces with suitable lens tissue and approved lens cleaner is recommended; the Euromex objective should be handled by trained personnel and stored in a dust-free environment when not in use.

Is the objective suitable for thick or irregular samples?
Due to the short 1.5 mm working distance, the objective is best for thin sections or surface inspections; thicker, irregular samples may require objectives with greater clearance.
