bScope BS.7140 Microscope Objective — 40×, NA 0.65 (Euromex)

The bScope BS.7140 is a 40× microscope objective engineered for close‑focus laboratory and educational microscopy applications, delivering a numerical aperture of 0.65 and a working distance of 0.64 mm.

• 40× magnification for detailed observation
• High numerical aperture 0.65 for improved resolution
• Short working distance 0.64 mm for close focusing
• Designed for laboratory and educational microscopes

Optimised optics for improved image detail

The objective combines a 40× magnification with a 0.65 numerical aperture, which together increase the system’s light‑gathering ability and resolution. A higher numerical aperture reduces diffraction limits and enables finer structural detail to be resolved from stained specimens and thin sections. This optical specification is particularly relevant where image clarity and contrast are essential for analysis, teaching or routine inspection.

Design that supports precise sample work

A working distance of 0.64 mm means the front lens is close to the specimen plane, enabling high‑power focusing on standard prepared slides. Short working distances demand careful sample handling but reward users with sharper focal planes and improved contrast at high magnification. For workflows where thin samples and fine structural detail are typical, this configuration delivers measurable benefits in outcome and throughput.

Practical suitability and common applications

The objective is intended for use with standard laboratory and educational microscopes and is referenced in both education and life‑science product documentation. Typical uses include biological teaching, routine cell observation and detailed inspection of prepared histological slides. The optical characteristics make the component well suited to situations where resolution and contrast are prioritised over working clearance.

Confidence in supply and ongoing support

Sourcing precision optics from a reputable line assures consistent performance in everyday use. Metav’s approach to democratising precision means reliable availability from the Emmerich distribution point and a broad selection of complementary microscope accessories.

FAQ

What magnification does this objective provide?
The objective offers 40× magnification; the Euromex bScope BS.7140 is therefore suited to tasks that require higher detail on prepared slides.

What is the numerical aperture and why does it matter?
The numerical aperture is 0.65; a higher numerical aperture increases light collection and resolution, which improves the visibility of fine specimen details under brightfield imaging.

How close can the objective focus to the sample?
The working distance is 0.64 mm, which enables close focusing on thin specimens and prepared slides while requiring careful sample clearance and stage adjustment.

Is this objective suitable for educational laboratories?
Yes. The objective is documented in education‑focused product material and is appropriate for teaching and demonstration where high‑magnification resolution is required.

What identifiers should be used when ordering or referencing the part?
Use the article number/SKU BS.7140 and reference the Euromex bScope series when specifying the objective.
