Unendlich IOS 45 mm Plan semi-apo PL‑SAMi 20/0.45 BD objective (M26)

The Unendlich IOS 45 mm Plan semi-apo PL‑SAMi 20/0.45 BD objective is an infinity‑corrected microscope objective optimised for high‑resolution laboratory imaging and industrial inspection where compact mounting is required

Infinity‑corrected optical design for compatibility
Plan semi‑apochromat correction for flat fields
0.45 numerical aperture for detail resolution
M26 thread for compact integration

Consistent high‑resolution performance for inspection tasks

The objective delivers a combination of 20× magnification and 0.45 NA, providing measurable improvements in resolving power for routine quality checks and documentation. The plan semi‑apochromat correction minimises field curvature, which preserves edge sharpness across the image and reduces post‑processing. This optical configuration supports reproducible measurements and clear visual inspection, translating into faster defect recognition and fewer retakes during throughput‑sensitive operations.

Compact mounting and predictable mechanical integration

Designed with an M26 thread, the optic is straightforward to integrate into instruments and adapters that accept compact objective fittings. The short 3.1 mm working distance is specified for close‑focus imaging, enabling precise observation of fine surface detail. The infinity‑corrected design separates the objective’s optical function from tube optics, which simplifies system configuration and allows the objective to be used with a variety of imaging tubes and camera adapters without compromising image formation.

Practical optical details and limitations explained

The objective is supplied without cover glass correction, which means the optical correction is optimised for specimens imaged without an intervening cover slip. Where cover glass thickness varies, alternative objectives with cover glass correction should be considered. The product’s model designation includes BD and the focal reference of 45 mm as part of the optical specification; these identifiers assist in matching the objective to an existing optical train and ensuring mechanical compatibility for stable, repeatable imaging.

FAQ

What numerical aperture and magnification does this objective offer?
The Euromex objective provides 20× magnification with a 0.45 numerical aperture, offering a balance between magnification and light‑gathering for high‑resolution imaging in inspection tasks.

Is the objective suitable for systems with M26 fittings?
Yes, the objective features an M26 thread and is designed for compact integration into systems and adapters that accept M26‑mounted objectives.

Does this objective include cover glass correction?
No, this model is supplied without cover glass correction and is optimised for imaging without an intervening cover slip; specimens requiring cover glass compensation will need a different objective.

Can the objective be used with infinity‑corrected microscope tubes?
The lens is infinity‑corrected, so it is compatible with imaging tubes and camera adapters intended for infinity optics, allowing flexible configuration with existing systems.

What is the working distance and how does it affect use?
The working distance is 3.1 mm, which is suitable for close‑focus inspections of surfaces and components; the short distance supports fine detail capture but requires careful sample handling.
