Abstract
A frame, termed a prism frame, is attached to a processing face of a prism assembly and used to hold a position of a compensating waveplate and a microdisplay. The compensating waveplate includes adjustment tabs that allow precise positioning of an orientation of the waveplate (e.g., waveplate angle, rotation, etc) such that it is best positioned to compensate for items like residual retardation and/or skew rays that occur in the kernel. The precise position is varied depending on kernel design and other factors. A microdisplay frame is attached to a microdisplay package. The microdisplay frame is then precisely attached to the prism frame. The microdisplay can be removed from the kernel by sacrificing the inexpensive microdisplay frame.
