Infinity IOS 45 mm plan semi-apochromatic 20x/0.45 BD objective (M26 thread, 3.1 mm working distance)

A Unendlich IOS 45 mm plan semi-apochromatic 20x/0.45 BD objective is engineered for high-detail brightfield and documentation tasks, suited to compact microscope systems requiring a short working distance

• 20x magnification for detailed imaging
• Numerical aperture 0.45 for enhanced resolution
• M26 thread for compact microscope compatibility

Consistent high-resolution imaging for demanding inspection

The lens delivers reliable, repeatable results thanks to its 20x magnification combined with a 0.45 numerical aperture, which together improve contrast and resolving power in moderate‑magnification inspections. The plan semi-apochromatic correction reduces field curvature and chromatic aberration, so structures remain sharp from centre to edge — a decisive advantage when capturing images for analysis or documentation. The optical design supports consistent measurement and visual assessment, reducing rework and increasing throughput on the bench.

Compact mounting and short working distance for tight setups

Designed with an M26 thread and a 3.1 mm working distance, this objective is suitable for compact or stacked optical assemblies where space is limited. The small mounting diameter enables integration into slim nosepieces or specialised adapters without major modification to existing stands. The brief working distance favours high‑numerical‑aperture performance in close‑range applications, making the lens appropriate for detailed inspection of small components, PCB areas and microscopy workflows that demand both precision and a reduced footprint.

Optical reliability that supports efficient workflows

The infinity-corrected optical concept encoded in the construction provides compatibility with common tube lens systems and helps maintain image quality when combined with intermediate optics or camera adapters. The semi-apochromatic correction and the BD designation in the model name indicate attention to aberration control and contrast — factors that streamline image processing and measurement routines. As a result, laboratories and production inspection stations benefit from quicker setup times and fewer calibration cycles.

FAQ

Is this objective compatible with standard infinity tube lenses?
The objective AX.8120 is an infinity-corrected design and is compatible with standard tube lenses used in infinity optical systems, provided the mechanical mounting and parfocal settings match the host microscope.

Can the lens be used for documentation with camera adapters?
Yes, the 20x objective is suitable for camera-based documentation when paired with the correct tube lens and camera adapter; the semi-apochromatic correction helps maintain image quality for digital capture.

What kinds of inspection tasks benefit most from this objective?
The short working distance and 0.45 numerical aperture make it particularly appropriate for detailed inspection of small parts, fine solder joints, surface structures and tasks that require high central sharpness and good field flatness.
