Euromex AE.5594 — 20x microscope objective, NA 0.40

The microscope objective AE.5594 is a 20x optical lens optimised for precise sample inspection and metrological imaging in laboratory and workshop environments.

• 20x magnification for detailed imaging
• Numerical aperture 0.40 for improved resolution
• Working distance 1.2 mm for close-up inspection
• Euromex quality for consistent performance

High‑resolution imaging that supports reliable measurement

The combination of 20x magnification and a numerical aperture of 0.40 delivers enhanced contrast and resolving power for fine structures. A larger numerical aperture gathers more light and narrows the diffraction limit, which means more detail is retained in the image; this is particularly beneficial when measuring features or assessing surface structures. The specification given in the Education PDF confirms the optical parameters (20x/0.40 SMP objective), so operators can rely on consistent imaging performance when integrating this lens into metrological workflows.

Close working distance tailored for detailed inspection tasks

A working distance of 1.2 mm enables very close focus on small or shallow specimens, supporting detailed observation and precise alignment during measurement. Close proximity to the sample reduces parallax and can improve measurement repeatability for flat or low‑profile parts. Care should be taken with fixturing and sample clearance because the short working distance requires controlled specimen placement; this trade‑off is common when pursuing high magnification and resolution in compact optical designs.

Practical use and workshop advantages for metrology setups

The objective is designed for routine use in inspection and quality control, offering a straightforward upgrade path for microscopes used in laboratories and industrial metrology stations. Euromex manufacturing standards aim to ensure mechanical consistency between objectives, which helps maintain calibration and reduces downtime. Regular cleaning with appropriate lens tissue and storage in a dry, dust‑free case will preserve optical performance and support reliable measurement results across repeated inspection cycles.

FAQ

What magnification does this objective provide?
The Euromex AE.5594 objective provides 20x magnification, suitable for detailed inspection and mid‑range metrology tasks.

How does the numerical aperture affect measurement quality?
A numerical aperture of 0.40 increases resolving power and light‑gathering capability, which helps to produce clearer images for more reliable measurements with the Euromex AE.5594.

Is the short working distance a limitation for workshop use?
The 1.2 mm working distance allows very close focus for fine detail; however, it requires careful specimen fixturing to avoid collisions and to ensure reproducible positioning during inspection.

Can this objective be used for both laboratory and industrial inspection?
Yes, the optical characteristics and Euromex build quality make the objective suitable for laboratory benches and industrial metrology stations where high‑resolution visual inspection is needed.

How should the lens be maintained to preserve accuracy?
Routine care such as gentle cleaning with suitable lens tissue and storing the objective in a dust‑free environment will help maintain optical clarity and ensure ongoing measurement reliability with the AE.5594.
