Abstract
An optical image splitter disposed in the path of image-bearing light along an optical axis has a coated dichroic surface disposed at an angle of 15 degrees or less relative to incident light along the optical axis. The coated dichroic surface has a number of layers of material, the of layers including layers having a first refractive index, n, and layers having a second refractive index, n, greater than the first refractive index. The coated surface transmits light of at least a first wavelength range to form a first image at an image plane and reflects light of a second wavelength range to form a second image at the image plane.
