Reliable low-power imaging that speeds routine inspections

The 4x setting of this low-power objective delivers a wide field of view that accelerates sample overview and specimen orientation, reducing time spent locating regions of interest. Its 0.10 numerical aperture offers a favourable balance between resolution and depth of field, which is advantageous when scanning slides or working with thicker preparations. The optical design supports consistent contrast and clear visual feedback, helping to maintain throughput in teaching labs and quality-control workflows while keeping image interpretation straightforward.

Practical handling and reduced risk at the stage

A 7.18 mm working distance gives a measurable clearance between the objective and the specimen, lowering the chance of accidental contact with slides or coverslips during focusing and manipulation. This objective is noted as a PLi objective in the technical documentation, indicating design choices that favour practical use in everyday microscopy. By combining a modest numerical aperture with a safe working distance, the optic supports robust handling protocols and reduces interruptions from re-centring or slide replacement, thereby contributing to steady workflow performance.

Trusted series-level performance for education and routine labs

Belonging to the BioBlue.Lab series from Euromex, this objective is positioned for general laboratory and instructional environments where dependable, repeatable imaging is required. The specification set—magnification, aperture and working distance—makes it well suited to overview imaging, live-sample observation and preparatory scanning before switching to higher-power objectives. Paired with consistent optical manufacture, the component supports standardisation across multiple microscopes, which simplifies training and reduces calibration variance within a teaching cohort or production line.

FAQ

What is the main application of this objective?
The BioBlue.Lab BB.7204 is designed for low-power overview imaging and routine microscopy tasks where a wide field of view and safe working distance are priorities.

How does a 0.10 numerical aperture affect image quality?
A 0.10 numerical aperture on this objective provides moderate resolution with an increased depth of field, making focus and specimen navigation easier compared with higher-NA, high-magnification lenses.

Why is a 7.18 mm working distance important?
A 7.18 mm working distance reduces the risk of contact with slides or samples during focusing and manipulation, improving operational safety and handling confidence.

Is the BB.7204 suitable for educational laboratories?
Yes, the specification and handling characteristics of the BioBlue.Lab BB.7204 make it well suited to teaching labs and routine inspection environments where robust, repeatable imaging is required.

Does the objective belong to a series with comparable optics?
The objective is part of the BioBlue.Lab series by Euromex, which groups optics with consistent handling and imaging characteristics for straightforward system standardisation.
