PL‑SAPOLRi 100x/0.90 plan semi‑apochromatic objective DX.7900-R (Euromex)

The PL‑SAPOLRi 100x/0.90 objective DX.7900-R is an infinity‑corrected lens for 60 mm optical systems, optimised for high‑resolution close‑range observation with an M25 mount

• Infinity‑corrected optical design
• 100x magnification, 0.90 numerical aperture
• 1 mm working distance for close detail imaging
• M25 thread for standard objective holders

High‑resolution detail where it matters

The combination of 100x magnification and a 0.90 numerical aperture delivers superior resolving power for fine structural detail. A high numerical aperture increases light collection and improves contrast at high magnifications, which is particularly beneficial when resolving sub‑micrometre features. The corrected optics ensure a flat field across the image, so resolution and image uniformity are maintained from centre to edge, reducing the need for extensive post‑processing. This makes the objective suitable for demanding inspection tasks in laboratories, routine industrial inspection and advanced teaching environments.

Compact integration on infinity‑corrected 60 mm systems

Built for infinity‑corrected optical systems with a 60 mm tube specification, the lens mounts via an M25 thread for straightforward installation into compatible nosepieces. The 1 mm working distance provides a very close sample approach, enabling high‑NA performance, but also requires careful sample handling and stage adjustment. The objective is specified without cover glass correction, so it performs optimally in setups where either no cover glass is used or where the optical train does not demand additional cover glass compensation. System planners should verify mechanical clearance and optical compatibility when integrating the lens into existing assemblies.

Stable colour rendition and suitability for unstained samples

The plan semi‑apochromatic correction reduces chromatic aberration and supports even colour rendition across the field, improving the visibility of fine structures without aggressive digital correction. The designation "dye‑free" indicates suitability for imaging unstained or intrinsically contrasted specimens, where inherent optical contrast is preferred. The optical design therefore benefits workflows that require faithful morphology visualisation rather than colour enhancement. Built to professional tolerances, this lens offers consistent performance for repeated inspections and contributes to reproducible imaging results in production control and research applications.

FAQ

Is this objective compatible with standard infinity‑corrected microscopes?
The PL‑SAPOLRi 100x/0.90 objective DX.7900‑R is specified for infinity‑corrected systems with a 60 mm tube specification; compatibility with the instrument must be confirmed by matching tube length and mechanical mount.

Does the lens include cover glass correction?
No — the DX.7900‑R is supplied without cover glass correction, so it is intended for use where a cover glass is not required or where the optical system provides the necessary compensation.

What does the dye‑free designation mean for application?
"Dye‑free" indicates suitability for imaging unstained or naturally contrasted samples; the objective preserves intrinsic specimen detail without reliance on staining for visibility.

Can the objective be mounted on standard M25 nosepieces?
Yes, the objective uses an M25 thread and fits holders and nosepieces designed for M25 objectives, subject to the instrument’s mechanical compatibility.

How does the 0.90 numerical aperture affect imaging?
A 0.90 numerical aperture increases light gathering and resolving capability at high magnification, improving contrast and the ability to resolve fine structures under appropriate illumination.
