BioBlue.Lab BB.8820 microscope objective — 20x, NA 0.40 by Euromex

BioBlue.Lab BB.8820 is a microscope objective engineered for clear mid‑range magnification imaging in educational and life‑science settings.

• High 20x magnification
• Numerical aperture 0.40 for resolution
• Working distance 1.20 mm for fine focus

Optimised mid‑range imaging for clear detail

The BioBlue.Lab BB.8820 offers 20x power and a numerical aperture of 0.40, a combination that increases light gathering and improves image resolution and contrast compared with lower‑NA optics. The numerical aperture describes how much light the objective can collect: a higher value translates into finer detail and brighter images at the same illumination. For laboratories that require dependable intermediate magnification—for example in cell observation, histology teaching or routine inspection—this lens delivers consistent optical performance while keeping adjustments straightforward.

Short working distance enables close inspection of thin samples

With a 1.20 mm working distance, the objective brings the front lens close to the specimen plane, permitting high‑detail observation of thin preparations and coverslips. A reduced working distance improves optical coupling between sample and objective, which enhances effective resolution, but it also requires careful stage movement and sample handling. The compact clearance benefits applications where maximum image detail is important and sample thickness is controlled, such as mounted slides in teaching labs or routine life‑science workflows.

Practical design for integration into educational and life‑science microscopes

Specified as a PL objective, this lens is suitable for standard microscope setups used in education and basic research. The objective’s design supports straightforward fitting on compatible microscope nosepieces and aligns with common illumination geometries to produce balanced images under transmitted light. Euromex quality control ensures the lens meets industry expectations for reproducibility, making it a practical choice for facilities that need reliable optics across multiple users and shifting experimental routines.

Improves throughput through consistent, reproducible results

By combining stable magnification, sufficient numerical aperture and a controlled working distance, the objective helps reduce repeat imaging and user‑related variability. This contributes to faster analysis cycles and fewer adjustments during session handovers, which is particularly valuable in shared laboratory environments and classroom settings. The result is an objective that supports precision and dependable imaging, helping teams to maintain steady workflows and reduce time lost to re‑setups.
