DeltaOptical Discovery 20x Stereoscopic Microscope
The DeltaOptical Discovery 20x stereoscopic microscope opens up an entirely different world of observation compared to classic biological microscopes. Instead of transparent specimens on glass slides, here you examine three-dimensional objects in their natural state - coins, stones, insects, plants, electronics, jewelry, or anything else that interests you. Simply place the object under the objective and immediately see its surface at twenty times magnification and in three dimensions, through both eyes.
What Is a Stereoscopic Microscope and What Is It Used For?
A stereoscopic microscope (sometimes also called a dissecting microscope or binocular magnifier) works differently than a standard biological microscope. You don't observe transparent specimens in transmitted light, but rather opaque objects illuminated from above. Each eye sees the object from a slightly different angle, which creates depth perception and three-dimensionality - just like normal vision.
This type of microscope is invaluable wherever you need to:
- Examine the surface of solid objects - structure, texture, details
- Work with the object under the microscope - soldering, dissecting, sorting
- Maintain spatial perception at magnification
- Observe without complex specimen preparation
Easy to Use - Ideal for Beginners and Children
One of the greatest advantages of the DeltaOptical Discovery 20x microscope is its absolute simplicity of use. Unlike classic biological microscopes, here you don't need:
- Slides and cover slips
- Preparation of thin sections or smears
- Complex focusing at high magnifications
- Special chemicals or stains
Simply find an interesting object, place it on the stage under the objective, turn on the LED illumination, and you can observe. This is why this microscope is suitable even for children who can use it independently without constant adult assistance. Finding something interesting, placing it under the microscope, and examining it - anyone can do that.
Binocular Observation - Comfort for Your Eyes
The microscope has two eyepieces, so you observe with both eyes simultaneously. This is a huge advantage over monocular microscopes - your eyes tire less, observation is more pleasant, and most importantly, you get stereoscopic vision. Surface relief, heights and depressions are clearly visible, which is the fundamental feature of stereoscopic microscopes.
The interpupillary distance is adjustable in the range of 55-75 mm, so you can adapt the microscope to your head. The left eyepiece also has diopter correction of +/- 5 diopters, which allows you to compensate for any difference in vision between your left and right eye.
What Can You Observe?
The possibilities are almost limitless. A stereoscopic microscope finds applications in many areas:
For Collectors and Numismatists
Coins, banknotes, postage stamps - all these items reveal details under the microscope that you can't see with the naked eye. You'll determine the true condition of a piece, detect wear and scratches, but also fine details of minting or printing. For collectors, this is an essential tool for determining value and authenticity.
For Geologists and Mineral Collectors
Stones and minerals show their true beauty. Crystal structure, colours, lustre, inclusions - all of this appears in a completely different light under the microscope. You can observe fracture surfaces, identify minerals by their physical properties, or simply admire the beauty of nature in miniature scale.
For Young Naturalists
Insects, spiders, snails, plant parts - all of these are fascinating objects for observation. Unlike a classic microscope, here you see the insect whole, in space, with its body segments, appendages, wings. A plant leaf shows its venation, hairs, stomata. A seed reveals its structure. Tree bark, moss, lichen - all of these are small worlds waiting to be discovered.
For Hobbyists and Electronics Enthusiasts
Soldering small components, checking connections on circuit boards, assembling small parts - in all these activities you'll appreciate the magnification and stereoscopic vision. The working distance of 80 mm provides enough space to work with tools under the microscope.
For All the Curious
Textiles - fabric structure, individual fibers. Paper - fibers, manufacturing method. Money - security features. Jewelry - quality of workmanship. Photographs - print structure. Food - salt and sugar crystals, bread structure. Anything you can think of!
Technical Design and Build Quality
The microscope has a metal body that guarantees stability and long lifespan. Plastic microscopes loosen over time, joints become loose, and focusing stops working precisely. Metal construction prevents these problems.
LED illumination is positioned above the object and illuminates it from above - so-called epi-illumination or reflected light illumination. LED diodes provide bright, white light that faithfully reproduces colours, doesn't heat up, has a long lifespan, and consumes minimal energy. You can power the microscope either from a 220V mains adapter or from batteries, which allows you to use it away from electrical outlets - in the field, at exhibitions, when working outdoors.
The working distance of 80 mm is sufficient for comfortable observation as well as for working with objects under the microscope. You can manipulate the object, use tweezers, a scalpel, or other tools without bumping into the objective.
Camera Connection Capability
Using an optional 30mm adapter, you can connect a digital eyepiece camera or professional microscope camera to the microscope. This is mounted in one of the eyepiece tubes instead of an eyepiece. You thus gain the ability to photograph and record videos of your observations.
This is useful for:
- Documenting your collections or findings
- Sharing discoveries with friends or on social media
- Educational purposes - showing others what you see
- Comparing objects over time
- Creating presentations and professional materials

Why Choose This Microscope?
The DeltaOptical Discovery 20x stereoscopic microscope offers an ideal combination of quality, simplicity, and affordability. It's not a toy - it's a genuine optical instrument with a metal body and quality optics. At the same time, it's not unnecessarily complicated or expensive. The 20x magnification is optimal for most common uses - you see enough detail, but still have a reasonably wide field of view and large working distance.
LED illumination with the option of battery power means you can use the microscope anywhere. The binocular head ensures comfortable observation and stereoscopic vision. And the ability to connect a camera opens up additional possibilities for documentation and sharing.
If you're looking for a microscope that won't just sit in a box in a closet, but which you'll actually use to discover and explore the world around you, the DeltaOptical Discovery 20x is an excellent choice.
