Stepped Grating
Processing Capacity
Capable to realize the complete processes in optical design, instrument design, component high-precision molding,
planar processing, spherical processing, aspheric processing, coating, etc.
Applications
Photoelectric information; aerospace; new energy; nuclear power and nuclear energy equipment and other fields.
Performance
● High-resolution stepped grating is designed for application to a high order special low-period grating . It is usually
used with another grating or prism realize the overlapping diffraction orders separation.
● The stepped grating is made of precise glass substrate and theoretically has a resolution of 80% to 90%. With a
high flare angle, it is an ideal choice for high-resolution spectral applications.
