Open Platform
Build, modify, and share your microscope
The full open-source ecosystem: 3D-printable cube designs, electronics schematics, firmware (ESP32), and ImSwitch software. Build your own microscope from scratch, customize every component, and share your designs with the community.
Everything you need to build
All resources are free and open source. No registration required.
Hardware designs (CAD)
All cube modules, baseplates, and assemblies as open-source STL/STEP files. Print on your own 3D printer or order from our shop.
Electronics schematics
PCB designs for the UC2 electronics stack: motor drivers, LED controllers, and ESP32-based mainboard. KiCad and Gerber files included.
Software (ImSwitch)
Python-based microscopy control software with GUI, REST API, and Jupyter integration. Runs on Raspberry Pi, Jetson, or any PC.
Configurator tool
Drag-and-drop web tool to design your optical setup. Export a bill of materials and assembly instructions.
Documentation
Comprehensive build guides, API references, and tutorials. From your first cube to automated whole-slide scanning.
Community
Join 500+ builders on our Discourse forum. Share your designs, get help, and collaborate on new modules.
From the community
Real projects built by real people around the world
Incubator microscope
A PhD student in Berlin built a time-lapse microscope that sits inside a CO2 incubator. Uses ESP32 WiFi for remote control.
Community build
Automated blood smear scanner
A clinic in Nigeria assembled a brightfield scanner from 3D-printed cubes and a Raspberry Pi. Scans malaria samples at 10x.
Community build
DIY light-sheet microscope
A group of undergrads in Munich built a light-sheet microscope for their thesis project, including a custom sample chamber. Total cost under EUR 500.
Community buildDIY or buy ready-made?
You don't have to choose. Mix and match.
Build it yourself
- + Maximum flexibility
- + Lowest cost (3D printing + off-the-shelf parts)
- + Full understanding of every component
- + Can modify anything to fit your specific use case
- - Assembly time required
- - Quality depends on your 3D printer
Buy from the shop
- + Injection-molded cubes (precision, durability)
- + Pre-tested optics with quality assurance
- + Ready-to-use — unbox and start building
- + Support and warranty from openUC2
- - Higher upfront cost
- - Fixed set of components
Ready for a professional upgrade?
The FRAME microscope uses the same cube architecture — but with motorized stages, precision machining, and automated software. Your open-source skills translate directly.
