A spectrometer is a photometer that detects the composition of substances by passing light through a sample and comparing before and after wavelength intensities. The instrument performs over a range ...
Researchers from the University of Cambridge and GlitterinTech, a startup founded by the same research group, have unveiled a ...
University of Illinois chemistry professor Alexander Scheeline has developed software that turns a camera phone, an LED, and a few other cheap tools into a spectrometer. Armed with these, he thinks we ...
Researchers have miniaturized a spectrophotometer onto a single chip that can analyze any wavelength of visible light and part of the infrared spectrum (Science 2021, DOI: 10.1126/science.add8544).
What can you make with a toilet paper roll, duct tape, and a graphing calculator? A stand for your homemade spectrometer. This is neither as pretty nor as accurate as a precision scientific instrument ...
