Using a right-angle prism, the two halves are joined to create a dispersing prism with an internal right angle bend obtained by total internal reflection. See Figure 1. Photo 2 A simple dispersing prism always deviates the longer wavelength less than the shorter wavelength. In a Pellin Broca prism, whether the longer wavelength is deviated more or less depends on the orientation of the prism. This is an important consideration when designing a high power Pellin Broca beam separator. This is illustrated in Figures 2 and Figures 3.
