Planachromatisch PLM 20x/0.40 LWD IOS Objective — Objective / Lens by Euromex, 20×, NA 0.40

The Planachromatisch PLM 20x/0.40 LWD IOS objective is a planachromatic microscope objective intended for detailed transmitted-light inspection of uncovered or thin samples, offering a long-working-distance design and no cover glass correction.

• Planachromatic correction for flat field
• 20× magnification with 0.40 numerical aperture
• Long working distance 4 mm
• No cover glass correction for uncovered samples

Enhanced flat-field imaging for reproducible results

The planachromatic design delivers a flat field across the visual area, reducing edge curvature and ensuring that structures stay in focus from centre to periphery. This optical correction improves image uniformity and simplifies measurement tasks in routine inspection. By lowering field curvature, the lens reduces the need for frequent refocusing during stage scans and supports reliable visual assessment and documentation workflows. Such optical stability is particularly beneficial where consistent documentation and comparative imaging are required.

Suited for uncovered samples and close-focus applications

With a long-working-distance configuration and omission of cover glass correction, the objective is optimised for samples prepared without a coverslip or for applications where a coverslip would interfere with the specimen. The absence of cover glass correction means optical performance is prioritised for direct sample observation rather than compensated for additional glass thickness. The working distance characteristic allows safer clearance between sample and lens, useful for thicker specimens or for setups requiring additional manipulation space while maintaining optical performance.

Practical compatibility and workshop-grade reliability

The lens features an IOS optical system and a robust mechanical mount designed for repeated use in laboratory and vocational environments. Its mechanical and optical build supports stable alignment and longevity in busy microscopy suites. Supplied by Euromex and distributed via Metav, the component integrates into typical optical benches and standard microscope turrets when thread and tube-length match; compatibility checks are advised prior to fitting. The compact, purpose-built construction balances handling convenience with reliable optical output for inspection, teaching or light industrial tasks.

FAQ

What benefit does a planachromatic objective provide compared with standard optics?
A planachromatic objective reduces field curvature and chromatic aberration, so images remain sharp across the field; the Euromex Planachromatisch PLM objective offers consistent edge-to-edge clarity for reliable inspection.

Can this objective be used for preparations with a coverslip?
This objective has no cover glass correction, so optical performance is optimised for uncovered samples; using a coverslip will alter the imaging plane and may require an objective designed for cover glass compensation.

Is the lens appropriate for industrial inspection and teaching laboratories?
Yes — the Euromex objective combines flat-field correction and a robust mount suited to repeated use in teaching, inspection and light industrial environments; check mechanical compatibility with the microscope turret before fitting.

How can the OX.8220 be integrated into an existing microscope?
Integration depends on the microscope’s objective thread and tube specification; confirm compatibility with the Euromex Planachromatisch PLM 20x/0.40 LWD IOS objective and Metav can advise on mounting and system matching.
