Unendlich EIS 60 mm Plan semi-apo PL-SAPOLRi 50x/0.80 — 50x Plan Semi‑Apochromat Objective (M25, 0.3 mm WD) by Euromex

The Unendlich EIS 60 mm Plan semi-apo PL-SAPOLRi 50x/0.80 is a high‑resolution objective designed for industrial and laboratory microscopes, offering precise imaging with M25 thread mounting.

• 50x high-resolution objective
• Numerical aperture 0.80 for high detail
• M25 thread for compact mounting
• Plan semi-apochromat correction for flat field

Exceptional resolution for detailed inspection

The optic delivers 50x magnification combined with a 0.80 numerical aperture (NA), which improves light-gathering and contrast for small feature detection. As an infinite‑corrected objective for an EIS 60 mm system, the design transfers an accurately collimated image to the microscope tube, enabling consistent imaging across different tube optics. The plan semi‑apochromat correction reduces field curvature and chromatic aberration across the visible spectrum, so critical inspection tasks show improved edge sharpness and colour fidelity. This combination of features supports reliable, repeatable measurements and visual assessments in a production or R&D environment.

Compact mounting and mechanical integration benefits

The M25 thread simplifies installation where space is limited or where specialised adaptors are required; the small footprint suits modular trinocular heads and compact inspection systems. The objective’s 0.3 mm working distance is engineered for close-focus applications and high‑numerical‑aperture performance; such a short working distance enhances resolution but requires careful sample clearance planning. The compact thread size and defined mechanical interface enable straightforward exchangeability, reducing machine downtime and streamlining calibration procedures in a workshop or lab.

Clear guidance on optical compatibility and use cases

This lens is supplied without cover‑glass correction, so specimens should be imaged without a standard cover slip or with a correction collar on the intermediate optics when cover glass is present. As a plan semi‑apochromat objective, it is well suited to metallurgical inspection, electronics assembly inspection and biological preparations where flatness and reduced chromatic error are priorities. The infinite‑corrected architecture allows the objective to be combined with a range of tube lenses and camera adapters for digital capture, offering flexibility for both visual control and automated image acquisition workflows.

Reliability, procurement and workflow advantages

Manufactured to industry standards, the optic offers a focused balance of performance and integration ease that supports efficient process control. Choosing this Euromex objective through Metav Werkzeuge provides access to a European supply channel and technical advice from a partner experienced in metrology and workshop equipment. The predictable optical behaviour and standardised mechanical interface reduce setup iterations and support a smoother route to production‑grade imaging, contributing to fewer rejects and more reliable inspection records.

FAQ

What magnification and resolution can be expected from this objective?
The Euromex Unendlich EIS 60 mm Plan semi‑apo PL‑SAPOLRi 50x/0.80 objective delivers 50x magnification with a high 0.80 numerical aperture, offering enhanced resolution and contrast for fine detail inspection.

Is this lens suitable for imaging with a cover slip?
The objective is supplied without cover‑glass correction; using a cover slip will introduce spherical aberration unless compensated by the microscope’s intermediate optics or a correction mechanism.

Which microscopes is the M25 thread compatible with?
The M25 thread provides a compact mechanical interface compatible with heads and adaptors that accept M25 objectives; compatibility should be confirmed against the microscope’s objective mounting specifications and any adaptor requirements.

Can this objective be used for digital camera capture?
Yes, as an infinite‑corrected objective for an EIS 60 mm system, the optic pairs with appropriate tube lenses and camera adapters for digital imaging, enabling integration into automated inspection setups.

What is the impact of the 0.3 mm working distance on sample handling?
The short 0.3 mm working distance improves numerical aperture performance but necessitates careful sample clearance and fixturing to avoid contact between objective and specimen.
