Spectrophotometer or Spectrometer: An Overview

This page provides a fundamental understanding of spectrophotometers and spectrometers. It covers the basics, key benefits, features and highlights reputable vendors and manufacturers in the field.

What is a Spectrometer?

In physics, a spectrometer is an instrument designed to measure the electromagnetic (EM) spectrum. This spectrum is typically represented as a graph with wavelength on the X-axis and intensity on the Y-axis.

When the spectrometer is used specifically within the optical domain (visible light and related wavelengths), it is often referred to as a spectrophotometer.

Spectrophotometer Explained

A spectrophotometer is used to measure the properties of light over a specific range within the electromagnetic spectrum. It has a wide range of applications:

• Astronomy: Analyzing radiation emitted from astronomical objects to understand their composition and behavior.
• Chemical Analysis: Determining the chemical composition of samples by analyzing their light absorption and transmission properties.
