A spectrophotometer consists of a light source, a monochromator to select specific wavelengths, a sample holder, and a detector. The light source emits a beam that passes through the monochromator, which isolates a particular wavelength. This beam then interacts with the sample, and the detector measures the intensity of transmitted or absorbed light. The resulting data provide valuable information about the sample's optical properties, which is crucial for understanding and manipulating nanomaterials.
