StereoBlue SB.3903 – Trinocular stereomicroscope with 7–45× zoom and LED ring illumination (Euromex)

A StereoBlue SB.3903 stereomicroscope for detailed inspections and imaging, designed for laboratory, quality control and educational applications

• Trinocular 45° head for camera attachment
• Continuous zoom 7–45× for flexible magnification
• 100 mm working distance for large samples
• Ring and transmitted LED illumination

Precision optics for flexible inspection

The optical system delivers a 7–45× magnification range via a 0.7–4.5× zoom objective, providing a 29.9–4.6 mm field of view that supports both overview checks and fine-detail work. The combination of zoom and wide-field eyepieces permits rapid switching between scales of observation without changing lenses; this reduces inspection time and minimises handling. The binocular head includes WF 10×/21 mm eyepieces and bi‑directional dioptre adjustment, allowing operators with differing vision to focus quickly and maintain accuracy. The 100 mm working distance ensures comfortable manipulation of components under observation while preserving depth perception and image stability.

Reliable illumination and documentation-ready

Lighting is specified as an LED ring light with 30 LEDs plus LED transmitted illumination, giving consistent, low‑heat illumination for extended sessions and sensitive samples. The trinocular, 45° head makes the instrument immediately suitable for documentation workflows; with the appropriate SLR adapter the top port accommodates a camera for microphotography. Note that additional SLR adapters (e.g. AE.5025, AE.5040) or a compatible photo connection and sensor size (SB.9850) may be required depending on the camera system. This setup supports traceable image records and rapid report generation, improving process control and quality assurance in routine inspections.

Ergonomic stand and practical accessory package

A rack‑and‑pinion stand provides smooth vertical adjustment and stable positioning for repetitive inspection tasks, while the adjustable interpupillary distance (55–75 mm) and bilateral dioptre control aid operator comfort and reduce fatigue. The instrument is supplied with practical accessories: eyecups, dust cover, instruction manual, mains lead and spare fuse, enabling immediate setup and protected storage. The optical and mechanical design emphasises durability and predictable performance, which makes the microscope suitable for both workshop environments and teaching labs where consistent results are required.

FAQ

What magnification range is available and how versatile is it?
The StereoBlue SB.3903 offers 7–45× magnification via a 0.7–4.5× zoom objective, enabling quick transitions from overview to detailed inspection without lens changes.

Is the microscope suitable for photodocumentation?
Yes, the trinocular, 45° head is designed for camera use; the StereoBlue SB.3903 accepts an SLR adapter (e.g. AE.5025 or AE.5040) depending on the camera bayonet and may require the specified photo connection or sensor size for SB.9850.

How does the lighting support inspection of different materials?
A combination of a 30‑LED ring light and LED transmitted illumination provides even, low‑heat lighting suitable for a wide range of specimens, improving contrast and reducing glare for metals, polymers and biological samples.

What ergonomic features reduce operator fatigue during long sessions?
Adjustable interpupillary distance (55–75 mm), bilateral dioptre control and a comfortable working distance (100 mm) make the instrument easier to use for different operators and minimise posture‑related strain.

Which accessories are included for immediate use?
The delivery for the StereoBlue SB.3903 includes eyecups, a dust cover, an instruction manual, the mains lead and a spare fuse to ensure prompt commissioning.
