Abstract:
A mechanical grating device for diffracting an incident light beam has a base which defines a surface. A spacer layer is provided above the base, said spacer layer defining an upper surface of said spacer layer. A longitudinal channel is formed in said spacer layer, said channel having a first and second opposing side walls and a bottom. The side walls are substantially vertically disposed with respect to the bottom, and said channel having a constant cross section along the entire length of the mechanical grating device.
