ABSTRACT:
Optical devices and related methods are provided. One example of the optical device includes two or more optical members joined together to form a stack. Each of the optical members in the stack includes a reflecting surface that has a corresponding slope, where the slope of each reflecting surface is different. In addition, disposed on each reflecting surface is a material that is reflective for a particular wavelength of light, so that each optical member reflects a different wavelength, and so that the optical members in the stack are able to collectively image the reflected signals onto a two dimensional detection plane.
