Planachromatic PLM 10x/0.25 LWD IOS Objective — Long working distance microscope lens by Euromex

A Planachromatic PLM 10x/0.25 LWD IOS Objective is designed for polarised-light microscopy, offering a balance of flat-field imaging and extended sample clearance for routine laboratory and industrial inspection

• Planachromatic correction for flat field
• 10× magnification, NA 0.25
• 10 mm long working distance
• No cover-glass correction included

Easier handling of thicker or mounted samples with extended clearance

The combination of a 10 mm working distance and 10× magnification gives measurable handling advantages during sample preparation and observation. The increased clearance permits easier use of larger specimens, manipulation tools and polarising accessories without sacrificing image stability. For workshops and inspection benches this translates into faster sample changes and reduced risk of accidental contact with objectives, supporting uninterrupted workflows and efficient throughput.

Reliable image flatness and contrast for polarised-light tasks

The planachromatic design corrects field curvature across the image plane, so structures at the edge remain as sharp as those in the centre. With a numerical aperture of 0.25, the objective balances depth of field and resolving power for routine materials analysis under polarised light. This combination yields consistent contrast and clarity for tasks such as mineral identification, petrography or failure analysis where even illumination and accurate planar representation are essential.

Designed for infinity-corrected systems and no cover-glass setups

Engineered for an infinity-corrected optical system (IOS), the lens integrates with many modern microscope stands that use tube lenses for image formation. It is supplied without cover-glass correction, indicating optimisation for direct-sample observation or for use with specific sample holders rather than standard cover-slip thicknesses. This makes the objective particularly suitable for metallographic preparation, bulk specimens and other applications where a cover glass is absent or variable.

Practical fit for laboratories, education and light industrial inspection

The lens delivers a pragmatic mix of optical performance and durability that suits teaching labs, routine quality control and entry-level materials laboratories. The moderate aperture and robust working distance reduce the need for constant fine adjustment, helping less experienced operators achieve repeatable results while experienced users appreciate the predictable imaging behaviour. Compatibility checks with existing stands are straightforward; technical specifications provide the basis for quick integration decisions.

FAQ

What applications suit this objective best?
The objective is optimised for polarised-light observation and routine materials inspection; the Euromex planachromatic lens performs well for petrography, metallography and general sample analysis.

Can this objective be used with coverslips?
This lens is supplied without cover-glass correction, so imaging with standard cover slips may require accommodation or selection of an objective with the appropriate correction.

Is the lens compatible with infinity-corrected microscopes?
Yes — the design follows an infinity-corrected optical system (IOS), enabling integration with compatible modern microscope stands.

How does the numerical aperture affect image quality?
A numerical aperture of 0.25 provides a balance between resolution and depth of field, giving clear detail at 10× while maintaining useful focus tolerance for uneven samples when using the Euromex objective.

Does the working distance allow additional accessories under the lens?
The 10 mm working distance offers practical clearance for polarising filters, micro-manipulation or coarse sample adjustments without risk of contacting the lens surface.
