Infinity-corrected Plan Apochromat PL‑AMi 50x/0.80 Objective (Euromex) — M26, 1 mm working distance

The Infinity-corrected Plan Apochromat PL‑AMi 50x/0.80 objective is a high‑magnification microscope lens designed for applications requiring exceptional resolution and field flatness in industrial and laboratory inspection

• Infinity-corrected optics for stable imaging
• High 0.80 NA for improved resolution and brightness
• Plan apochromat correction for flat field imaging
• M26 thread for compact instrument integration

Outstanding resolution for fine detail and fast results

The PL‑AMi 50x/0.80 objective delivers a significant step up in resolving power compared with lower‑NA lenses. With a numerical aperture of 0.80, the lens captures more light and resolves finer structures, which translates into clearer, more contrasted images under reflected or transmitted illumination. This performance is especially relevant for applications where defect detection, metrology or microstructure analysis must be precise and repeatable. The optical design minimises chromatic aberration, so colour fringing is reduced across the field, enabling reliable measurements and easier interpretation of microscopic features.

Flat field performance reduces re‑focusing and increases throughput

As a Plan Apochromat, the lens is corrected to present a flat image plane across the usable field of view. This means less time spent compensating for curvature of field when scanning across a specimen and fewer focus adjustments during routine inspection. For process environments where throughput matters, the flatter field reduces operator intervention and helps automated imaging systems maintain focus across stitched images or large‑area scans. The combination of plan correction and high NA therefore supports both visual inspection and quantitative imaging workflows.

Compact mounting and clear mechanical specifications

The objective features an M26 mounting thread, which accommodates compact microscope noses and many inspection attachments, offering straightforward mechanical integration into existing stands and imaging systems. A working distance of 1 mm indicates the lens is optimised for close‑up observation of surfaces or thin samples; care in sample preparation and stage control is advisable to avoid contact. The specification "without coverslip correction" makes the optical characteristics clear: the lens is intended for samples not viewed through a standard coverslip, so it suits surface inspection or reflected‑light setups where no cover glass is present.

Practical considerations for laboratory and industrial use

Due to the short working distance and high magnification, stable specimen mounting and precise z‑axis control are essential to exploit the lens’s capabilities reliably. The objective’s design focuses on delivering high contrast and fine detail rather than long working range, so it pairs well with precision stages, immersion techniques where applicable, or specialised illumination to enhance feature visibility. When integrating into imaging chains, match the objective with a suitable tube lens and camera sensor to preserve field flatness and resolution; correct system matching ensures the optical advantages of the lens are realised in measurements and images.

FAQ

What magnification and resolution can be expected with this objective?
The PL‑AMi 50x/0.80 objective provides 50× magnification with a 0.80 NA, offering high resolution and improved brightness suitable for detailed inspection and metrology tasks.

Is the objective suitable for samples under a coverslip?
This objective is specified without coverslip correction, so it is intended for use on samples without a coverslip, such as surface inspections or reflected‑light applications.

How close must the objective be to the sample during imaging?
The working distance is 1 mm; precise stage control and secure mounting are recommended to avoid contact and to maintain focus at this close range.

Which thread is used to mount the objective?
The objective employs an M26 mounting thread for integration into compatible microscope noses and compact inspection assemblies.

Can this objective be used for automated imaging or stitching large areas?
Yes — the Plan Apochromat design provides a flat field that reduces refocusing across the image, making it suitable for automated scanning and stitched imaging when paired with appropriate stages and control systems.
