Advanced Grating Products in Precision Optics

An optical grating is a precision optical component that utilizes periodic microstructures to achieve light diffraction, spectral separation, and spectral analysis. It serves as a fundamental device in modern optical systems for wavelength selection, spectral measurement, and beam manipulation. By fabricating regularly spaced grooves or micro/nano-periodic structures on a substrate surface, gratings utilize the diffraction characteristics of light at different wavelengths to disperse incident light into spectral signals directed at various angles. They are widely used in fields such as spectroscopy, laser systems, optical communications, scientific research, industrial inspection, and aerospace.Our grating products are manufactured using high-quality optical substrates—including glass, fused silica, and specialized optical crystals—combined with advanced precision ruling, holographic exposure, and coating processes. These products feature high diffraction efficiency, high resolution, e…
