Spectrometer 

Spectrometer ( Spektrometer)

Spektrometer (spektrofotometer, spektrograf atau spektroskop) adalah alat yang digunakan untuk mengukur ciri cahaya pada bahagian tertentu spektrum elektromagnet, lazimnya digunakan dalam analisis spektroskopik untuk mengenal pasti bahan. 

A spectrometer is a scientific instrument used to separate and measure spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were developed in early studies of physics, astronomy, and chemistry.
