FWHM Calculator

About This Tool

The FWHM Calculator is a specialized online tool that enables users to compute the Full Width at Half Maximum of spectral lines or signals. Designed for astronomers, researchers, and optical professionals, it simplifies complex data analysis by offering quick, reliable calculations based on user-input parameters or spectral data fitting.

Users can enter peak intensities, background levels, and noise parameters to obtain immediate FWHM results. For advanced analysis, the tool accepts spectral data points to fit Gaussian or Lorentzian profiles, generating both the FWHM value and visual curves to aid interpretation.

This tool is ideal for observational astronomers analyzing star spectra, physicists working with laser or emission data, and optical scientists optimizing system parameters. Its features support high-precision measurements, trend analysis, and data export, making it a vital part of scientific data workflows.

Designed with a clean UI and accessibility in mind, the calculator ensures usability across devices, with options for dark mode, results history, and multi-language support. It enhances productivity by providing instant, accurate spectral analysis results in a user-friendly environment.
