A single beam spectrophotometer is an analytical instrument used to measure the absorbance or transmittance of light by a sample at a specific wavelength. It operates using a single light path, where measurements of the blank and sample are taken separately, making it simple, cost-effective, and suitable for routine laboratory analysis.
