SUS Interface

MOUNTING FLATS
Flatness: l/10 - Sheila Rowan et al / Physics Letters A 246 (1998) 471-478
Dimensions: < 95 mm x full width - Peter Fritschel  T040008, "Optical loss due to suspension mounting flats"
Tolerances: same as SF2 penultimate mass D040278-01

AOS Interface

COATINGS
All coatings (HR and AR) are to be > 5% reflective
at 675nm,
for angles of incidence between 0° and 45°,
for both polarizations, p and s
