Euromex BioBlue.Lab BB.7240 microscope objective — 40x, NA 0.65

BioBlue.Lab BB.7240 is a 40x microscope objective engineered for high‑resolution observation in life‑science and education settings, offering a compact working distance for close‑focus imaging.

• 40x magnification for detailed observation
• Numerical aperture 0.65 for high resolution
• 0.68 mm working distance for close focusing

Exceptional resolution for routine and advanced imaging

The combination of 40x magnification and a 0.65 numerical aperture provides a noticeable improvement in resolving fine specimen detail compared with lower‑NA objectives. In practical terms, the higher aperture increases light collection and contrast, making subcellular structures more distinguishable under transmitted light. This makes the lens particularly suitable for biological staining techniques and brightfield microscopy where image clarity and contrast are decisive for analysis. The optical specification is documented as S40x/0.65 PLi in the manufacturer literature.

Optimised for close‑range sample work and precise focusing

A working distance of 0.68 mm indicates that the front lens element sits close to the specimen plane, enabling compact optical paths and efficient use of light at higher magnifications. This short distance supports detailed observation of thin preparations and coverslip‑mounted samples, but requires careful stage and condenser adjustment to avoid contact with the specimen. The objective is designed to integrate into existing optical systems where space and numerical aperture are limiting factors, offering a balance between magnification and signal quality for routine laboratory workflows.

Practical compatibility and application notes

Supplied specifications identify the unit as a dedicated microscope objective within the BioBlue.Lab series; it is referenced in the Education and Life Science PDFs as suitable for educational and research use. As a precision optical component, alignment, tube length and turret fitting are determining factors for compatibility with a given microscope stand. The BB.7240 is intended for users seeking improved detail at medium‑high magnification and benefits applications in teaching laboratories and basic research where contrast and resolution are priorities. For specimen types, the optical properties favour standard biological preparations rather than thick or highly three‑dimensional specimens.
