1 1 SuperCam Optics & Mount Design Dathon Golish 8/2/06 Zemax Optical Design: Converts the SMT f/13.8 beam to f/5 to match SuperCam Large Flat:.75 m x.55 m Hyperbola: R = 1692 mm; k = -3.05;.5m x.5m Flat Fold:.1 m x.1 m Ellipse: R = 772 mm, k = -0.03;.4m x.4m Large Flat Hyperbolic Mirror Elliptical Mirror Flat Fold Detector Plane 77 mm Quartz Field Lens (not pictured, doubles as dewar window): R = -1800

2 2 ASAP Optical Analysis Incoming Beam – Gaussian with 14 dB edge taper on dish Total energy reaching detector:82% – 89% Coupling between ideal Gaussian and energy profile reaching detector: 92% – 93% Total: 75% - 83% Total energy reaching detector:82% – 89% Coupling between ideal Gaussian and energy profile reaching detector: 88% – 92% Total: 72% - 82% For comparison, the DesertSTAR focus (with no added optics except a flat tertiary) gave: Energy: 89% Coupling: 97% Total: 88% Results for extended horns option:
