Plan apochromatic PL‑AMi 100x/0.90 IOS BD objective by Euromex — high‑resolution laboratory imaging, M26 mounting

The Plan apochromatic PL‑AMi 100x/0.90 IOS BD objective is a high‑performance microscope objective designed for demanding brightfield and metallurgical applications where optical correction and mechanical consistency are essential

*Plan apochromatic correction for sharp imaging *High magnification: 100x, NA 0.90 *Short 1 mm working distance for immersion setups *M26 thread, 45 mm parfocal compatibility

Exceptional optical resolution for demanding inspection

The plan apochromatic design delivers a flat field and strong chromatic correction, reducing colour fringing across the field of view. With 100x magnification combined with a numerical aperture of 0.90, the lens increases resolution and contrast for fine-detail inspection. This optical performance benefits tasks such as microstructure analysis or high‑magnification quality control by improving feature separation and image fidelity, making metrology and documentation more reliable.

Compact working distance matched to specialised workflows

A 1 mm working distance provides the precise proximity often required in immersion or high‑power metallurgical arrangements; this short distance supports high numerical aperture performance while keeping the sample within the optimal focal region. The absence of cover glass correction is explicitly specified, ensuring consistent focus when imaging without a coverslip. The parfocal height of 45 mm stabilises focus when switching objectives, reducing adjustment time and supporting efficient laboratory throughput.

Mechanical compatibility and quick integration into existing stands

The M26 mounting thread and the standard parfocal length ensure straightforward replacement or upgrade of existing optical assemblies. The robust mechanical specification simplifies integration into inspection microscopes and documentation systems that accept M26 objectives, avoiding custom adapters and reducing downtime. Consistent parfocality helps maintain alignment across objective turrets and speeds up multicriteria inspection routines.

Practical explanation of key specifications for decision making

Numerical aperture (NA) denotes the light‑gathering ability; a 0.90 NA allows finer resolution but requires careful illumination. The plan apochromatic correction corrects spherical and chromatic aberrations across multiple wavelengths, yielding sharper, colour‑accurate images across the field. The specified working distance and omission of cover glass correction are deliberate choices for particular sample preparations; verify compatibility with the intended sample mounting and illumination method before integration.

FAQ

What applications is this objective best suited for? This Euromex objective (PL‑AMi 100x/0.90 IOS BD, SKU DI.8100) is suited to high‑resolution brightfield and metallurgical inspection where plan apochromatic correction and a high numerical aperture are required.

Is the objective corrected for use with cover glasses? No. The specification states the objective has no cover glass correction, so it is intended for imaging without a coverslip; check sample mounting before selection.

Can this objective be fitted to a standard microscope turret? Yes. The objective uses an M26 mounting thread and a 45 mm parfocal length, facilitating integration into stands that accept M26 objectives and standard parfocal heights.

How does the numerical aperture affect imaging with this lens? The 0.90 NA increases resolution and contrast but requires appropriate illumination; higher NA improves detail detection at the expense of shallower depth of field.
