Euromex Unendlich IOS 45 mm planapochromatisch 50x/0.80 BD Objective (M26 thread)

A precision objective lens from Euromex offering 50x magnification with a 0.80 numerical aperture, optimised for high-resolution microscopy and compact inspection setups.

• Infinity-corrected, 45 mm design
• Plan-apochromatic correction for flat-field imaging
• High numerical aperture 0.80 for better light collection
• M26 mounting with 10 mm working distance

Precision optics that improve measurement reliability

The infinity-corrected, 45 mm optical concept provides a stable basis for modern imaging chains. With a plan-apochromat design, the lens corrects field curvature and chromatic aberration across the image field, which results in consistently sharp images. The 50x magnification paired with a 0.80 numerical aperture enhances detail and contrast, making the lens suited to demanding inspection and documentation tasks where optical fidelity directly affects measurement reliability. The performance characteristics support high-detail observation without frequent refocusing.

Practical compatibility and straightforward integration

Mechanical and optical compatibility are central to efficient system design. The M26 thread simplifies mounting into compact microscope stages and many inspection heads; the 10 mm working distance permits close approach to samples while preserving clearance for fixtures or probing equipment. Being infinity-corrected means the lens is compatible with tube lenses and camera adapters designed for infinity systems, enabling flexible integration into both visual and camera-based setups. This combination reduces setup time and improves process throughput in production environments.

What the optical figures mean for everyday use

A 0.80 numerical aperture increases the lens’s light-gathering capacity and potential resolving power compared with lower-NA objectives; practically, this yields brighter images and improved detail when lighting is constrained. The plan-apochromat correction reduces colour fringing and keeps the image flat across the field, which is particularly beneficial for metrological tasks and high-resolution photography. The designation BD in the type indicates a specific performance variant provided by the manufacturer, while the compact working distance supports inspection of small components where space is limited.

FAQ

What does infinity-corrected mean for optical compatibility?
Infinity-corrected systems place the image at infinity before the tube lens; the Euromex AX.8150 is designed for such systems, allowing use with compatible tube lenses and camera adapters.

How does a plan-apochromat benefit metrology and imaging?
A plan-apochromat objective minimises field curvature and chromatic aberration, so the AX.8150 provides a flat field and reduced colour fringing—advantages for measurement and high-resolution documentation.

Is the 0.80 numerical aperture suitable for low-light inspection?
Yes; the 0.80 NA increases light collection and image brightness compared with lower-NA objectives, improving contrast and detail in moderate lighting conditions.

Will the M26 mounting work with standard microscope adapters?
The M26 thread is a compact mechanical standard; compatibility depends on the instrument’s nosepiece or adapter. The mounting allows straightforward integration into many bespoke inspection rigs.

What is the practical effect of the 10 mm working distance?
A 10 mm working distance permits close inspection of small components while maintaining clearance for probes, fixtures or lighting—useful in assembly and quality-control tasks.
