2. Working Principle
2.1 Basic Concept
Wavelength measurement devices work on the principle of measuring the distance between two consecutive points of an electromagnetic wave in terms of wavelengths. This can be achieved through various methods, including spectrophotometry, interferometry, or the use of optical spectrum analyzers.
2.2 Components of the Device
Wavelength measurement devices typically consist of a light source, a sample or medium that interacts with light, a detector, and a display or data output system. These components work together to measure the wavelength of light accurately.
2.3 Operation of the Device
The light source emits light of a known wavelength, which passes through the sample or medium. The interaction between the light and the sample alters the properties of the light, such as intensity or phase. The detector captures these alterations and converts them into an electrical signal. This signal is then processed and displayed as the measured wavelength.

3.1 Spectrophotometer
A spectrophotometer measures the amount of light absorbed or transmitted by a sample at different wavelengths. This device utilizes the principles of spectrophotometry, which involves passing a light beam through a sample and comparing the intensity of the incident and transmitted light to determine the sample’s absorption or transmission characteristics.
3.2 Interferometer
Interferometers are used to measure the wavelength of light by splitting the light beam into two or more paths, recombining them, and analyzing the resulting interference pattern. The measured change in interference patterns can be used to accurately determine the wavelength.
3.3 Optical Spectrum Analyzer
An optical spectrum analyzer measures the power distribution of light over a specific wavelength range. By using a diffraction grating or other dispersion elements, it separates the incident light into its component wavelengths and analyzes their power levels.
