What Makes the Olympus SZH10 Special

The Olympus SZH10 is a classic, professional-grade stereo microscope that remains a favorite among researchers and educators. Even though it’s an older model, this unit has been fully refurbished by our team and still features optical and mechanical quality that rivals many modern microscopes.

This particular microscope setup includes both brightfield and darkfield illumination, making it versatile for a variety of applications — from crystallography and metallurgy to dissection, circuit board inspection, and biological observation.

What Is a Stereo Microscope?

A stereo microscope (or stereoscope) provides a three-dimensional view of your sample. Unlike compound microscopes, which are designed for viewing slides at very high magnification, stereo microscopes are ideal for examining larger, solid objects in real time.

They’re often used for:

• Gem and crystal inspection

• Biological dissection

• PCB and solder joint analysis

• Forensic and geological work

• Quality control and materials inspection

Key Features Explained

1. Coarse and Fine Focus:
The SZH10 offers both coarse and fine focusing knobs. The coarse focus helps you quickly bring your sample into general view, while the fine focus allows for subtle adjustments to achieve sharp detail.

2. Interpupillary Distance:
This is the spacing between the eyepieces, adjustable to match your own eyes. Properly setting your interpupillary distance prevents eye strain and ensures a clear, merged 3D image.

3. Zoom Range:
The SZH10’s zoom range gives you flexible magnification options — allowing users to easily shift from a broad overview to a close-up look at surface structures and textures.

4. Illumination:
This microscope uses a 12-volt, 50-watt halogen bulb, delivering bright, consistent lighting for both brightfield and darkfield viewing modes. In the video, Chad demonstrates how to safely change this bulb, one of the most common maintenance questions we get.
