MicroBlue MB.7040 — Microscope objective, 40x magnification, NA 0.65 (Euromex)

The MicroBlue MB.7040 is a 40x microscope objective designed to deliver enhanced resolution and light-gathering capability for brightfield and general laboratory observation.

• 40x magnification for detailed observation
• Numerical aperture 0.65 for improved resolution
• Part of the MicroBlue objective series
• Euromex optical quality and consistency

Improved detail and resolution for demanding visual tasks

With a numerical aperture (NA 0.65), this optical element increases the amount of light collected from the specimen, which directly improves resolution and image contrast. The higher NA reduces diffraction limits, allowing finer structures to be distinguished at 40x magnification. In practical terms, the objective supports clearer visual separation of adjacent features and delivers more reliable images for standard laboratory assessments and teaching demonstrations. The relationship between aperture and resolving power is a fundamental optical principle: larger NA values enable finer detail to be resolved without changing magnification.

Reliable imaging in routine laboratory and educational settings

Engineered as part of the MicroBlue range, the lens is intended for frequent use in educational laboratories and general microscopy suites where consistent performance matters. The optical specification S40x/0.65 indicates an emphasis on optical performance at medium magnification, balancing field of view, working distance and image clarity. For users with a basic working knowledge of microscopy, the result is a predictable visual outcome that eases specimen analysis and reduces time spent on re‑adjustment during sessions, supporting efficient workflows and steady throughput.

Clear technical advantages that support workflow efficiency

The combination of 40x magnification and NA 0.65 provides a concrete efficiency advantage: fewer adjustments are required to obtain high‑contrast images, which reduces time per sample and increases laboratory throughput. The objective’s specification is well suited to applications where mid‑level magnification must reveal subcellular or fine morphological detail without the complexity or cost of higher‑power objectives. Because the functional details are explicit in the technical data, selection decisions can be made on an objective, evidence‑based basis and integrated into existing microscope systems with confidence.

FAQ

What does the numerical aperture 0.65 mean for image quality?
A higher numerical aperture, such as 0.65 on this microscope objective, increases light collection and improves resolution and contrast, enabling finer structural detail to be resolved at 40x magnification.

Is the MicroBlue MB.7040 suitable for educational use?
Yes. The MicroBlue MB.7040 objective is designed for routine laboratory and educational environments where consistent, reliable mid‑power imaging is required.

Which magnification range is appropriate for this objective?
The specification indicates 40x magnification; this objective is best used where medium magnification is needed to observe cellular structures and fine morphological details.

Can this objective be used on most standard upright microscopes?
The MicroBlue MB.7040 is supplied as a standard microscope objective suitable for use with microscopes that accept standard objective fittings; verify compatibility with the instrument’s nosepiece and tube length specification.

How does the S40x/0.65 designation affect selection?
The S40x/0.65 label describes the optical design and performance at 40x with NA 0.65, which helps in choosing an objective that balances resolution and light throughput for the intended application.
