Etymology
'spectrophotometer' originates from the combination of 'spectrum' and 'photometer', where 'spectrum' refers to a range of wavelengths and 'photometer' is an instrument for measuring light intensity.
'spectrophotometer' evolved from the combination of the words 'spectrum' and 'photometer' in the early 20th century to describe an instrument that measures light intensity across different wavelengths.
Initially, it meant 'an instrument for measuring light intensity', and this meaning has largely remained the same in modern usage.
