Microscope objective bScope BS.8740 — 40x magnification, NA 0.65 (Euromex)

The Microscope objective bScope BS.8740 is an objective lens for laboratory and life‑science microscopy, optimised for high numerical aperture imaging and precision short‑focus applications.

• 40x magnification for detailed imaging
• Numerical aperture 0.65 for higher resolution
• Working distance 0.66 mm for close focus

Sharper details through a high numerical aperture

A numerical aperture (NA) of 0.65 significantly increases light collection and angular acceptance compared with lower‑NA objectives, which directly improves resolution and image contrast in transmitted‑light and high‑detail observation tasks. In practical terms, this means finer structural detail is resolved at the sample plane, reducing the need for repeated scans and accelerating image‑based inspections. The optical performance is ideally suited to applications where visual clarity and measurement certainty influence downstream decisions in quality control and research.

Optimised for close‑range, high‑resolution inspection

The short working distance of 0.66 mm places the front lens very close to the specimen, enabling higher numerical apertures and tighter focus on thin samples, coverslips or surface features. Such proximity benefits applications that demand exceptional spatial resolution, though it requires careful focusing and awareness of sample clearance during setup. For routine laboratory workflows, the compact focal geometry supports precise imaging of microstructures while helping to keep optical path lengths short for stable, repeatable results.

Consistent optical performance for laboratory workflows

At 40x magnification, the objective delivers a practical balance between field of view and detail, making it suitable for a variety of analytical and inspection tasks within microscopy-equipped workshops and laboratories. Built as part of the bScope series, the component is intended to integrate into standard microscope turret systems, offering predictable imaging characteristics from sample to sample. Where repeatability and traceable observation matter, this objective contributes to faster decision cycles and fewer inconclusive inspections; Metav’s product specialists can assist with mounting and alignment considerations.
