China Optical Grating Manufacturer
Optical gratings are precise optical components that use a series of equally spaced lines or grooves to disperse light into its component wavelengths.
By diffracting and interfering light at specific angles, gratings enable accurate spectral analysis and wavelength separation. They are widely used in spectrometers, laser systems, optical communication, and scientific research.

Plane Holographic Reflective Grating
A plane holographic reflective grating is an optical diffraction element fabricated using the holographic interference exposure technology. Compared with the traditional gratings, the surface lines of the holographic grating are more uniform. Also, it typically has a sinusoidal groove profile and are generated by the recording of an interference pattern onto a photoresist-coated substrate. Features…

Reflective Ruled Diffraction Gratings
What are Reflective Ruled Diffraction Gratings? The Reflective Ruled Diffraction Gratings are optical components formed by mechanical etching on a reflective substrate. Theoretical resolving power is directly proportional to the number of grooves per millimeter ruled into the master grating. Therefore, they use the regular line structure to diffract and split the incident light. Due…
