01 / OVERVIEW

Diffraction grating for your application

A diffraction grating is an optical component with a periodic structure that diffracts incident light and separates wavelengths through controlled diffraction. Grating period and profile influence dispersion, wavelength response, and diffraction efficiency. Diffraction gratings are available in reflection and transmission configurations for different spectral applications.

Strahl Optics supports diffraction gratings manufactured using ruled and holographic processes, with grating structures selected to suit different spectral performance requirements. Careful optical inspection helps verify key grating characteristics and diffraction performance.
