Paper Abstract

The optical and mechanical design of a derotator unit employing a Delta prism are described. Comparisons with other derotation prisms demonstrate the space and weight advantages of the Delta in collimated light. Curves showing the dependence of input FOV and apex angle on refractive index are presented. The small size and single-piece construction of the D elta facilitate a mounting design which is environment resistant and enables precise adjustment.
