A bearnsplitting assembly that divides a single visible beam into three channels was designed, developed and produced. Each channel receives a spectrally balanced beam with equal intensity and color differences. The spectral and intensity balancing was achieved by application of two neutral bearrisplitters at 4S angle of incidence and a third surface with a total internal reflection (TIR). A simple method to design neutral dielectric bearnsplitters is shown and the design considerations are described. This bearrisplitter is particularly suitable for dividing a single beam into biocular observation in the case where the dimensions of the beaxnsplitting element is limited.
