bScope BS.8200 microscope objective — 100x, NA 1.25 (Euromex)

The bScope BS.8200 is a high-power microscope objective optimised for oil-immersion applications, designed for demanding life-science and educational imaging where fine structural resolution is required.

100x magnification Numerical aperture 1.25 Designed for oil immersion Working distance 0.36 mm

Exceptional resolution through high numerical aperture

The optical design centres on a numerical aperture of 1.25, which directly improves light-gathering capacity and resolving power. At 100x magnification, this combination enables finer detail to be distinguished than lower-NA optics, making the objective suitable for tasks that require visualising subcellular structures or minute surface features. The term numerical aperture refers to the lens’s ability to collect light and determine resolution; higher values translate into greater detail and contrast under identical illumination.

Practical considerations for oil-immersion imaging

A working distance of 0.36 mm means the front lens sits very close to the specimen; handling must therefore be deliberate to avoid contact with the sample. The lens is specified as an oil immersion type, so a thin layer of immersion oil is used between the cover slip and the objective to match refractive indices and eliminate air gaps. This improves image fidelity at high magnification. Users should ensure stable mounting and fine focus control when employing this objective to benefit from its high-magnification capabilities.

Integration, reliability and workflow benefits

Produced by Euromex and belonging to the bScope series, the lens is intended to integrate into standard upright microscope nosepieces where oil objectives are required. Its optical characteristics support reproducible imaging and consistent measurement results, which helps maintain throughput in routine laboratory work. The objective’s specifications favour applications in microscopy teaching, clinical preparations and research where precision and dependable optical performance are essential.

FAQ

What level of detail can be expected with this objective?
The bScope BS.8200 delivers high-resolution imaging at 100x magnification with a numerical aperture of 1.25, enabling clear visualisation of fine structural details that lower-NA optics cannot resolve.

Is immersion oil required for correct use?
Yes, this objective is specified for oil immersion; a thin layer of immersion oil between the cover slip and the lens is necessary to achieve the stated optical performance.

How close does the lens sit to the specimen during use?
The working distance is 0.36 mm, so careful focus control and sample mounting are recommended to prevent contact between the front lens and the specimen.

Is the objective compatible with standard microscope nosepieces?
The bScope BS.8200 is designed for standard nosepiece mounting on microscopes that accept oil-immersion objectives; compatibility should be confirmed against the instrument’s objective thread and turret arrangement.

Where can the product be ordered or specified further?
The objective is listed under SKU BS.8200; technical queries and procurement can be addressed via Metav Werkzeuge, which can assist with integration and delivery details.
