Product details
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, excellent spectral performance, and stable, reliable mechanical characteristics, meeting rigorous requirements for wavelength range, resolution, and optical throughput across diverse applications.

Based on manufacturing processes and structural characteristics, our gratings include types such as ruled gratings, holographic gratings, blazed gratings, transmission gratings, and reflection gratings. Ruled gratings, formed by precision mechanical ruling to create regular grooves, offer high diffraction efficiency and are ideal for high-performance spectroscopic systems. Holographic gratings, produced via interference exposure technology, provide low stray light and superior wavefront quality, making them suitable for precision instruments and scientific research equipment. Blazed gratings feature optimized groove profiles that concentrate optical energy into specific diffraction orders to enhance system efficiency, finding wide application in laser technology and spectral measurement.

We offer grating products with various groove densities, operating wavelength ranges, and dimensions to meet specific customer needs, covering spectral ranges from ultraviolet (UV) and visible (VIS) to near-infrared (NIR) and infrared (IR). We also provide customized design services—including specifications for grating size, groove density, blaze angle, coating type, and optical parameter optimization—to satisfy the unique requirements of different equipment and application environments. These products feature superior surface quality, high wavefront accuracy, excellent environmental stability, and long-term operational reliability. They are widely used in Raman spectrometers, fluorescence analysis equipment, laser measurement systems, spectroscopic detection instruments, semiconductor inspection equipment, biomedical analysis instruments, and scientific research platforms.

Leveraging advanced optical fabrication technology, a comprehensive quality inspection system, and extensive experience in custom development, we are dedicated to providing customers with high-performance, high-precision, and highly reliable grating products and specialized optical solutions, thereby continuously driving the advancement of spectroscopy technology and the optoelectronics industry.
