High Efficiency Reflection Grating 1200 Line/mm

We provide the replication copied from the master grating. Grating has the same performance at a lower price. A diffraction grating is an optical device exploiting the phenomenon of diffraction. It contains a periodic structure, which causes spatially varying optical amplitude andor phase changes. Most common are reflection gratings, where a reflecting surface has a periodic surface relief leading to position-dependent phase changes. However, there are also transmission gratings, where transmitted light obtains position-dependent phase changes, which may also result from a surface relief.
