A research team from the University of Strathclyde in Glasgow has developed a low-cost microscope that can be produced for around 60 US dollars. The design is based on the OpenFlexure platform, an open-source solution for microscopes, and combines 3D-printed parts with commercially available components such as a camera, a light source and a Raspberry Pi for control. Assembly takes less than three hours and the entire device weighs just 3 kilograms.
A key feature of this design is the use of transparent, 3D-printed plastic lenses. These enable microscopic examinations at cell level, for example of blood or kidney samples from mice. This is remarkable, as conventional laboratory lenses often cost thousands of dollars. The affordable design opens up access to high-quality microscopy for new target groups.
Compared to existing solutions, the Strathclyde microscope represents a significant cost reduction. A similar design by Gary Croft from 2022 required additional components and cost around 390 US dollars. The new model offers comparable functionality for less than a quarter of the price, making microscopes more accessible to schools, small labs and medical facilities in resource-poor regions.
Another advantage of the design is the use of 3D printing technology. This promotes local production and reduces delivery times and transportation costs. This is particularly useful for remote areas or in crisis situations.
The quality of the microscope is impressive. In tests, researchers were able to examine subcellular structures and anatomical details that were previously not visible with other inexpensive microscope solutions. The ability to build such a powerful device at a fraction of the usual cost could change access to microscopy worldwide.
