Plane Reflection Gratings

A plane reflection grating is an optical component that utilizes the periodic structure of its surface to diffract and disperse incident light, offering high diffraction efficiency and excellent spectral resolution. Such gratings are widely used in spectrometers, monochromators, Raman spectroscopy systems, optical analytical instruments, and scientific research equipment.
We offer a wide range of planar reflective gratings available in various specifications—including different wavelength ranges, groove densities, and application requirements—to meet the needs of high-precision spectral analysis and measurement applications.
