Coatings and Optics

This is a work in progress area for what optic and coatings we need.

Parameter	ITMs	ETMs	PRM	SRM	FM (4x)
HR Transmission 1064 nm	0.014 *	10 ppm	0.055 +/-0.003	0.10 +/- 0.005	<0.01
HR Transmission 532 nm	< 1000 ppm	0.10	n/a	n/a	n.r.
AR Reflection 1064 nm	< 1000 ppm	< 100 ppm	< 300 ppm	< 300 ppm	<0.01
AR Reflection 532 nm	<0.01	< 1000 ppm	n/a	n/a
ROC	Flat (>5 km)		57.5 m?	96.3 +50/-0 (96**)	117.1+50/-20 (116.3**)	inf
Wedge angle	1 deg (+/- 0.2 deg)	1 deg	1 deg	1 deg	1 deg

BR BR* T_ITMnom = 0.014 +/- 0.002. All 3 ITMs in the same coating run to match the T, i.e. T_ITMY - T_ITMX < 0.0003. Tolerance in T_ITMnom is larger. ** Based on ETM and ITM ROC, assuming inf. thin optics.
