Introduction and Overview
What is the FRAME Microscope?
The FRAME (Fast Rigid Automated Microscope Engine) represents a new approach to microscopy: an open, modular, automated, and flexibly adaptable microscope system. Based on the modular optics construction kit UC2 (You.See.Too.), the FRAME system lowers barriers to access complex optical and microscopy technology.
System Philosophy
Modular Design Principles
The FRAME system is built on complete modularization of all components regarding mechanics, electronics, and software:
- Interchangeable Modules: Cube modules can be freely exchanged to switch between brightfield, fluorescence, or interference microscopy
- Flexible Mechanics: Allows both classical objective setups and free arrangement for special geometries
- Smart Electronics: Each cube can optionally have its own control unit for motors, galvo mirrors, or LEDs. All components share the same CAN BUS via 12V supply voltage.
- Open Interface: System control via user-friendly graphical interface or programming interface (Python, REST, CAN BUS, USB)
Key Innovation Areas
- Accessibility: Open-source hardware and software increase transparency, longevity, and interoperability
- Automation: Open system allows straightforward automation with built-in APIs for software control, camera integration, and laboratory automation
- Modularity: Instead of purchasing a completely new microscope, users can exchange or expand individual modules
- Cost Efficiency: Compared to proprietary complete systems, costs are reduced by 50-90% depending on configuration

Sustainability and Environmental Impact
Resource Conservation
The modular approach contributes to sustainability on multiple levels:
- Repair & Maintenance: Instead of disposing of complete systems, only individual modules are replaced or adapted
- Upgrading: When components become outdated or new functions are needed, individual modules can be upgraded rather than replacing the entire system
- Local Production: Many mechanical components are produced locally via 3D printing using renewable materials
Open Source Benefits
- Global Accessibility: Electronic platforms can be replicated worldwide, including in resource-limited regions
- Knowledge Sharing: Open documentation promotes global access to high technology
- Community Development: Active community ensures continuous improvement and support
- Local Repairs: Using 3D printing and digital fabrication, broken parts can be repaired on site
