Set the spectrophotometer to a wavelength of 325 nm. (This is the lowest wavelength available for the Genesys 20 spectrophotometer.) Press 0 ABS/100%T to set the blank to 0 Absorbance. Place a thin ...

The idea of a spectrophotometer is simple enough – shine light through a sample, send that light through a diffraction grating, focus it, and shine the light onto a CCD.

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 ...
