Unendlich IOS 45 mm plan semi-apochromat 5×/0.15 BD Objective (M26) by Euromex

The Unendlich IOS 45 mm plan semi-apochromat 5×/0.15 BD Objective is a low-magnification microscope objective designed for general inspection and documentation tasks where a flat field and comfortable specimen access are required

• Infinity-corrected optical design
• 5× magnification with 0.15 NA
• Plan semi-apochromatic correction
• M26 mounting thread for compact microscopes
• 20 mm working distance for specimen access

Consistent low-power imaging that speeds inspection cycles

The optical unit delivers 5× magnification paired with a 0.15 numerical aperture, providing a balance between depth of field and resolution that is ideal for routine visual inspection and coarse measurement. The plan correction maintains image sharpness from centre to edge, which reduces the need for stage realignment and accelerates inspection throughput. As a result, process stability improves and repeatability of visual checks is enhanced without requiring time-consuming focus stacking or complex post-processing.

Compact compatibility for modern microscope systems

Built with an M26 thread and an IOS 45 mm tube geometry, the lens is intended for straightforward mechanical integration into compact trinocular heads and modular imaging assemblies. The infinity-corrected optical concept enables simple coupling to intermediate tube optics or camera adapters without significant compromise to image quality, while the 20 mm working distance allows safe handling of thicker samples or holders. These characteristics make the objective suitable for integration into inspection benches and documentation rigs.

Practical benefits for everyday laboratory and workshop use

Flat-field performance reduces artefacts at the edges and supports faster, more reliable documentation of serial samples. The combination of low magnification and a wide field of view enables efficient overview scans, minimising the number of fields required to inspect a component. Reduced operator fatigue and faster cycle times follow from the objective’s optical design, which is particularly advantageous in quality control, teaching environments and small-series production where time-to-decision is critical.

Installation guidance and specifications at a glance

Mounting is facilitated by the standard thread and robust mechanical tolerances; careful alignment with the tube lens and camera sensor yields optimal results. Routine cleaning with lens tissue and manufacturer-recommended solvents preserves coatings and ensures long service life.

FAQ

What magnification and numerical aperture does this objective provide?
The Euromex Unendlich IOS 45 mm plan semi-apochromat objective offers 5× magnification with a 0.15 numerical aperture, providing a useful compromise between field of view and resolving power for general inspection tasks.

How much working distance is available and why does it matter?
The objective has a 20 mm working distance, which allows clearance for thicker specimens, holders or probes and reduces the risk of collision during handling or measurement.

Is this objective compatible with camera attachments and tube optics?
Yes — the objective is infinity-corrected, so it is designed to work with intermediate tube lenses and camera adapters in standard imaging chains; verify thread and tube geometry compatibility using SKU AX.8105.

Which mounting thread does the objective use?
The lens uses an M26 mounting thread, a compact standard that fits many trinocular heads and modular microscope systems.

For which applications is this objective most suitable?
Its flat-field correction and low-power configuration make it well suited to routine visual inspection, documentation, teaching and coarse measurement tasks in laboratories and workshops.
