bScope BS.8420 microscope objective — 20×, NA 0.40 (Euromex)

bScope BS.8420 is a microscope objective designed for detailed observation in compact setups, offering a balance of resolution and working distance for educational and life-science applications.

• High 20× magnification for fine detail
• Numerical aperture 0.40 for brighter images
• Short working distance of 8.8 mm for compact setups
• Compatible with bScope series optical systems

High-resolution imaging with controlled light collection

The optical design delivers 20× magnification with a numerical aperture of 0.40, which directly affects resolution and light-gathering capacity. A higher NA increases the objective’s ability to resolve fine structure and improve image contrast under transmitted or reflected illumination. In practical terms, the combination of 20× and 0.40 NA yields crisp detail while maintaining sufficient depth of field for routine inspection tasks. The objective’s specification sheet notes the model as an IOS PLi 20×/0.40 design, which is typical for robust routine microscopy where clarity and repeatability are required.

Workspace efficiency and sample accessibility

A working distance of 8.8 mm provides a compact but usable gap between the lens front and the specimen, enabling accessory use and simple manipulation without compromising the optical plane. This 8.8 mm working distance is suited to standard sample preparations and thin sections; it allows for safe placement of slides and small coverslip-mounted specimens while ensuring focus stability. The objective’s geometry supports straightforward mounting in common microscope turret systems, permitting quick changes between magnifications in multi-objective setups and reducing downtime in workflow transitions.

Suitable for teaching and routine life-science tasks

Specifications and source notes indicate suitability for both educational and life-science environments, where consistent image quality and ease of use are priorities. The optical characteristics make this objective a practical choice for laboratory demonstrations, routine sample checks and comparative microscopy where reproducibility matters. The objective’s compatibility with the bScope series supports modular system planning, allowing a single optical platform to serve multiple tasks across bench and classroom applications.

Integration, maintenance and handling benefits

The objective is part of a coherent series intended for straightforward interchange and maintenance. The optical parameters listed—20×, NA 0.40, WD 8.8 mm—allow technicians to assess contrast, resolution and working clearance before installation, reducing compatibility queries. Regular cleaning with lens-safe fluids and lint-free tissues preserves optical performance; the compact working distance reinforces the need for careful handling during sample manipulation. For complex requirements, the specification references in the accompanying PDFs provide an authoritative source for verification.
