Let’s talk about one of our favorite stereo microscopes—the Zeiss Stemi 305. Whether you’re unboxing a brand-new model or setting up a pre-owned one from our inventory, there are a few key things you’ll want to know. A lot of what I cover here applies to the Stemi 508 as well, so buckle up and let’s dive in.
The Stemi 305: A Stereo Mic That Does It All
First, if you haven’t seen it yet, check out this quick video overview. In the video, I go over the basic parts of the Stemi 305—objectives, eyepieces, focus knobs, and stand features. One question I get a lot: How do I turn the lights on?! If you’ve ever stared at a Stemi 305 stand, wondering how in the world to power it up—don’t worry, you’re not alone. It’s like searching for a secret level in a video game. (Pro tip: The power button isn’t always where you think it is.)
The microscope in the video features a brightfield/darkfield stand—a versatile option that’s great for viewing different sample types. But depending on your needs, you can also choose from other stand options, including:
-
Plain and Illuminated Stands – For basic viewing and general-purpose work
-
Boom Stands – For large samples or when you need extra flexibility in positioning
What’s a Stereo Microscope Used For, Anyway?
Great question! A stereo microscope gives you a 3D view of your sample at lower magnifications—perfect for applications like:
-
Inspecting circuit boards and electronics
-
Dissecting small organisms in biology labs
-
Quality control in manufacturing
-
Jewelry or watch repair
-
Examining rocks, minerals, and fossils in geology
It’s the ideal tool when you need depth perception and a clear, wide view of your subject.
