An easy-to-make rainbow filter that could help users identify the true color of everything from paint to medicine has been named to the Society of Manufacturing Engineers (SME) list of 2013 Innovations that Could Change the Way You Manufacture.
This year’s list includes just five items, including the UB invention — an “everyday spectrometer.”
The technology is a rainbow-colored polymer that UB engineers created using a one-step, low-cost holographic lithography method. Employed as a filter for light, this polymer could form the basis of handheld multispectral imaging devices that identify objects’ “true color.”
Such accurate color detection could make it easier for governments to identify counterfeit money, for homeowners to match paint colors in renovation projects, and for doctors to analyze colors in medical images to detect disease. There are potential applications in fields from climate monitoring to remote sensing for military and defense.

The simple process for fabricating the polymer could make it feasible to develop small, low-cost, high-performance devices that connect with cell phones to conduct multispectral imaging. In addition, the filters can be produced at less than $10 apiece, making them a viable, state-of-the-art alternative to the much more expensive linear variable filters that are currently used for spectral analyses.
