Planapochromatic PL-AMi 50x/0.80 IOS BD objective (M26, NA 0.80) — Euromex

The Planapochromatic PL-AMi objective is a high-resolution lens designed for industrial inspection and reflected-light microscopy, pairing strong optical correction with a compact mounting format for turret systems

• Planapochromatic flat-field correction
• High numerical aperture 0.80
• M26 mount, 45 mm parfocal
• Short 1 mm working distance

Exceptional resolving power for fine-detail inspection

With a numerical aperture of 0.80, this planapochromatic lens delivers elevated resolution and improved light-gathering compared with lower-NA optics, enabling finer detail to be resolved on small components and microstructures. The planapochromatic design provides a flat field and advanced chromatic correction, which reduces colour fringing and sharpness fall-off at the edges of the image; the result is more consistent image quality across the field of view. These optical properties benefit metrology and quality-control tasks where measurement reliability and repeatable imaging are essential.

Compact mounting and parfocal compatibility for efficient workflow

The objective's M26 mounting and 45 mm parfocal length are chosen to match common turret and tube systems, allowing straightforward integration into existing microscope stands. The precise parfocal distance minimises refocusing when switching objectives, speeding up multi-magnification inspections and reducing cycle time in routine checks. The compact thread and mechanical design also support tight optical stacks where space is limited and stable mechanical alignment is required.

Designed for no-cover-glass applications and close-up work

Specified with a 1 mm working distance and no cover-glass correction, this lens is intended primarily for direct-surface inspection under reflected illumination rather than through standard cover slips. The short working distance favours high numerical aperture performance but requires careful sample handling and stage control; the trade-off is substantially greater lateral resolution and surface detail, making the objective suitable for electronics inspection, metallurgical observation and failure analysis.

Practical benefits for production and laboratory environments

The optical features of this lens translate into tangible operational gains: improved defect detection, reduced rework from clearer images and faster inspection routines through parfocal consistency. The robust mechanical interface and standard M26 thread support easy replacement and predictable alignment in instrument maintenance. Where precise visual assessment forms part of the quality chain, this objective contributes to more reproducible results and better documentation for traceability.

FAQ

What is the intended application for this objective?
The Planapochromatic PL-AMi 50x/0.80 objective is intended for reflected-light inspection tasks such as electronics, metallurgy and precision visual checks where close working distance and high resolution are required.

Can this objective be used with cover slips?
No — the lens is supplied without cover-glass correction, so it is optimised for direct-surface inspection rather than imaging through standard cover slips.

Which microscopes are compatible with the M26 mount and 45 mm parfocal?
Any microscope turret or tube system that accepts M26 threaded objectives and adheres to a 45 mm parfocal standard will be mechanically compatible; Metav Werkzeuge can advise on specific models and adapters.

How does the numerical aperture affect image quality?
A numerical aperture of 0.80 increases lateral resolution and light collection, improving detail contrast at high magnification; the short working distance supports this performance but requires careful handling.

Is this objective suitable for quantitative measurement tasks?
Yes — the planapochromatic correction and stable parfocal geometry support reproducible imaging, which assists quantitative inspection and traceable visual documentation when combined with calibrated imaging systems.
