TRANSMISSION DIFFRACTION DEVICE FOR HIGH DIFFRACTION ORDER AND METHOD OF FABRICATING THE SAME

摘要

A transmission diffraction device having a high diffraction order and a method of fabricating the same are provided. The diffraction device includes a light transmissible body, and at least one V-shaped groove formed in the light transmissible body. The V-shaped groove includes reflection and refraction planes. This diffraction device produces high-order diffracted light. As the diffraction order of the diffracted light becomes higher, the resolving power of the diffraction device can be improved.
