BioBlue.Lab BB.7200 microscope objective — 100x, NA 1.25, oil immersion (Euromex)

The BioBlue.Lab BB.7200 is a precision microscope objective designed for high‑magnification oil‑immersion work in education and life‑science routines.

• 100x magnification, high-detail imaging
• Numerical aperture 1.25 for resolution boost
• Oil‑immersion PLi design for contrast improvement
• 0.20 mm working distance for immersion use

Enhanced detail through high numerical aperture

The combination of 100x magnification and a numerical aperture of 1.25 translates directly into finer resolution and improved image contrast for translucent specimens. Numerical aperture measures the light‑gathering ability of the objective; a value of 1.25 (when used with an oil immersion medium) increases the objective’s resolving power compared with air objectives, allowing the observation of smaller structural details. This characteristic is especially relevant in cell biology and histology where identifying subcellular features depends on superior optical performance rather than simply higher magnification.

Stable oil‑immersion design for reproducible imaging

Constructed as an oil‑immersion PLi objective, the optical design is tuned to deliver consistent imaging across repeated sessions. The very short working distance of 0.20 mm is a direct consequence of the immersion configuration and supports close coupling between the cover glass and the front lens for maximal numerical aperture usage. For routine laboratory workflows, this geometry offers repeatable focus behaviour and stable contrast, which reduces the need for frequent adjustments during high‑magnification examinations and accelerates sample throughput in teaching or research environments.

Practical integration into teaching and life‑science setups

Part of the BioBlue.Lab series by Euromex, the BB.7200 objective is built to fit standard microscope nosepieces and to complement common condenser and illumination arrangements used in education and routine labs. The specification S100x/1.25 oil immersion PLi with WD 0.20 mm (source: Education PDF S.16; Life Science PDF S.12) allows straightforward verification against institutional optical requirements and ensures compatibility with typical laboratory procedures. The result is a reliable optical component that supports clear, high‑contrast images for demonstrations, documentation and analysis.

FAQ

What level of magnification and resolution does this objective provide?
The BioBlue.Lab BB.7200 is specified as a 100x objective with a numerical aperture of 1.25, delivering high resolution and enhanced contrast when used in oil‑immersion mode.

Is the BB.7200 suitable for routine teaching laboratories?
Yes, the Euromex BioBlue.Lab BB.7200 is designed for education and life‑science routines where high‑detail observation is required and fits standard microscope configurations used in teaching environments.

What does the working distance of 0.20 mm mean in practice?
A working distance of 0.20 mm indicates a very close distance between the front lens and the cover glass when correctly immersed; this enables the objective to achieve its full numerical aperture for optimal resolution.

Does this objective require special immersion oil or condensers?
The objective is an oil‑immersion PLi design; standard microscope immersion oils suitable for high‑NA objectives should be used and the condenser should be aligned for oil‑immersion techniques to realise the full optical performance.
