Welcome to the PF, Josh. :smile:

Can you post a few JPEG screenshots of your work? Many folks may be reluctant to open an Excel spreadsheet from an unknown source. Thanks.
 
Cross-section diagram of a compound parabolic concentrator: left parabola L and right parabola R meet at a truncation line, with focal points F_L and F_R, an absorber along the base, aperture A at top, axis lines, a vertical line, and labeled angles phi_1, phi_2 and 2theta_a, plus height h-bar and point (x-bar, y-bar).
am trying to come up with this drawing in excel
