Enhanced resolution through a high numerical aperture

A numerical aperture (NA) of 0.65 increases the lens’s light-gathering ability, which translates into sharper detail and improved contrast at high magnification. For routine laboratory tasks where distinguishing fine structural features is essential, the higher NA reduces diffraction limits and supports clearer imaging on transmitted-light setups. This optical characteristic benefits both microscopic documentation and careful visual assessment without demanding complex illumination upgrades.

Precise focusing enabled by the short working distance

The 0.66 mm working distance supports fine sample focus at 40x magnification, allowing close approach to thin specimens and coverslips common in education and life-science preparations. The compact clearance minimises parallax and helps maintain a stable focal plane during careful manipulations. For applications that require detailed observation rather than large sample clearance, this working distance provides a direct technical advantage in achieving crisp images of cellular and microstructural detail.

Consistent 40x performance for routine microscopy tasks

A stable 40x magnification setting offers predictable enlargement for documentation, teaching exercises and comparative observations. The optical construction delivers repeatable image scale for measurements and classroom demonstrations, helping technicians and instructors maintain continuity across sessions. The objective’s specification supports integration into standard microscope workflows where reliable mid-range magnification is required without frequent objective changes.

Designed for seamless integration in the bScope range

As part of the bScope series, this objective is specified as an S40x/0.65 IOS PLi type in the manufacturer documentation, indicating its intended role within Euromex’s optical lineup. The design focus is on dependable imaging quality and compatibility with common laboratory practices, which simplifies equipment selection and bench calibration. Documentation references list the key parameters, enabling straightforward comparison with alternative objectives when selecting optics for specific tasks.
