The SpecPhone: A 3D-Printed Smartphone Spectrophotometer for Research and Education

Visible absorption spectroscopy has a wide range of applications in chemistry labs, biomedical research, and clinical diagnostics. Our lab has developed the SpecPhone: a spectrophotometer that can be made with a 3D printer, some inexpensive parts, and a smartphone. The device can make analytically accurate measurements of concentration and can be used for education and DIY scientists.

More Recently we have upgraded the design to with a universal smartphone mount and dual beam optical geometry. We call this new version the DualSpec.
