Microscope objective bScope BS.8404 — 4× magnification, 21.0 mm working distance

Microscope objective bScope BS.8404 provides low-power imaging for rapid sample overview and easy positioning in education and routine laboratory tasks

• 4× magnification for overview imaging
• 21.0 mm working distance for sample clearance
• Numerical aperture 0.10 for moderate resolution
• Part of the bScope series for microscope use

Fast overview and straightforward sample access

The 4× magnification of this objective gives immediate overview imaging, ideal for locating regions of interest before switching to higher powers. The substantial working distance of 21.0 mm provides useful clearance between the lens and the specimen, reducing the risk of contact during coarse adjustments. With a numerical aperture of 0.10, the optic balances depth of field and resolving power, which helps maintain sharpness across uneven samples. This lens is particularly useful where fast navigation and robust handling are priorities.

Practical benefits for daily laboratory workflows

Engineered for straightforward handling, the objective shortens set-up time and cuts the need for frequent refocusing while scanning samples. The design supports consistent image quality across common lighting conditions and simplifies transfer between observation steps and documentation. As part of the bScope range from Euromex, the lens integrates into standard microscope workflows, enabling smoother inspection cycles and more efficient use of technician time in training rooms and routine analysis.

Where this objective fits and how to use it effectively

The optic is intended for general use with microscopes that accept standard objective mounts and is suitable for educational and life-science overviews where low-power, wide-field observation is required. The specification sheet notes the item as a 4×/0.10 IOS PLi objective with WD 21.0 mm, which underlines its role in rapid sample orientation and initial inspection. For further adaptation to specific stands or imaging systems, supplementary technical data can be provided to ensure correct matching and optimal performance.
