Up on Mars, the Curiosity Rover uses its spectrometers to examine the chemical composition of the rocks and dirt on the red planet. Now the Israeli startup Consumer Physics has developed a tool that lets you conduct similar experiments in your own backyard or at your dinner table.
The company launched a Kickstarter campaign today with the goal of raising US $200 000 to fund the first production run of its hand-held spectrometer, which is about the size of a flash drive. Using near-infrared spectroscopy, the device, called SCiO, shines light on a sample and measures the light absorption patterns of the molecules therein. It then identifies the object by its optical signature, and gives the user information about the object's molecular composition. It uses bluetooth to link to the user's smartphone, where an app manages the data.
