Explain about the Spectrophotometer?

The spectrophotometer, a key instrument today in biomedical laboratories, was invented in 1939 by the American chemist Arnold O. Beckman (1900-2004). It is a device which measures the amount of light absorbed by a substance. For example, vitamin A absorbs ultraviolet light so that a spectrophotometer can measure within minutes with almost perfect accuracy the amount of vitamin A in a given food.
