Infinity-corrected Plan APOLi 50x/0.80 objective (EIS 60 mm) — Euromex, M25 mount

The Infinity-corrected Plan APOLi 50x/0.80 objective is an optical lens designed for high-resolution microscopy applications, featuring an M25 mounting thread and integrated cover-glass correction for use with prepared specimens

• 50x magnification with high numerical aperture 0.80
• Infinity-corrected Plan APOLi optical design
• M25 mounting thread for compact microscope setups
• Cover-glass correction and 0.19 mm working distance

Exceptional resolution through optimised optical design

The infinity-corrected optical concept used here ensures that the objective delivers consistent imaging performance when paired with a matching tube lens. The Plan APOLi design corrects field flatness, so image sharpness extends across the field of view rather than only in the centre. With 50x magnification combined with a 0.80 NA, the lens increases lateral resolution and light-gathering capability, which results in clearer details on fine structures. This configuration benefits tasks that demand precise visual discrimination under transmitted-light microscopes, where enhanced contrast and resolution directly support reliable measurement and inspection results.

Compact mounting and mechanical compatibility for modular systems

The M25 mounting thread is a compact, widely used mechanical standard for supplementary objectives and modular microscope builds. A defined mounting like M25 simplifies mechanical integration into small-footprint or custom optical assemblies and reduces the need for adapter parts. The robust mechanical fit supports stable alignment, which is crucial when working at high magnification because even small shifts reduce image quality. The objective’s mechanical specification therefore contributes to a dependable optical chain and reduces downtime from repeated re‑adjustments.

Designed for cover-glass specimens and close working distances

This lens includes cover-glass correction, which reduces spherical aberration introduced by typical specimen mounting. The very short 0.19 mm working distance places the front element close to the sample plane, improving numerical aperture utilisation and image fidelity for thin preparations. As a result, the objective is particularly suited to inspections and imaging where specimens are mounted beneath a cover slip or other thin, transparent medium. The optical correction ensures that users gain consistent focus and contrast without complex adjustments for cover-glass effects.

Trusted supply and practical procurement for production environments

Sourced from a specialist optics manufacturer and distributed via Metav’s European supply channel, the component benefits from a quality-assured supply chain. Metav’s role acts as a practical quality filter for workshop and industrial customers, offering a broad range of measurement and imaging products from stock in Emmerich. For technical clarification on integration, optical pairing or to confirm compatibility with a specific microscope system, consult the manufacturer’s documentation or Metav’s technical advisors; standard contact options are available for further specification checks. This combination of tested optics and reliable distribution supports longer-term productivity and reduces procurement complexity.

FAQ

What mounting thread does this objective use? The objective uses an M25 mounting thread and is supplied as the Euromex Infinity-corrected Plan APOLi 50x/0.80 objective (SKU DX.7950-T)

What magnification and numerical aperture are provided? This lens offers 50x magnification with a 0.80 numerical aperture, optimised for high-resolution imaging

What is the working distance and why does it matter? The working distance is 0.19 mm; this short distance supports high numerical aperture performance but requires specimens to be prepared with appropriate cover-glass correction

Is the objective corrected for cover-glass use? Yes, the objective features cover-glass correction, reducing spherical aberration when imaging samples mounted under thin transparent media

What does EIS 60 mm indicate? EIS 60 mm denotes the objective’s optical variant as designated by the manufacturer; please refer to the Euromex product documentation for details on system compatibility
