6.1 Optics
6.1.1 System Optics
M3 Spare coating samples were sent for ellipsometetric measurement along with a large batch of system optics (M2 through M10) for ongoing system coating model monitoring. Both the polarization system model and the flux budget will be updated accordingly. Additional cleaning information was collected from the vendor for testing on large samples coated along with the M3 Spare.
The DSSC custom lab metrology system light source upgrade verification continues. Additional measurements show high spectral resolving power at sensitivity levels of parts-per-million level (OD6) are achievable, in some wavelengths achieving 10 parts per billion noise floor (OD8). Filter design verification at levels of for instrument filters is an ongoing effort. An example comparing Cryo-NIRSP filter theory to delivered optics is below. NDSP6 is the 6-simultaneous-spectrograph DSSC lab metrology system.

...
Some cold filters and samples have been sent for long wave IR throughput measurements to an outside vendor. Analysis of the DSSC data package on filter spatial transmission and blocking is ongoing.
A diffused, F/24 three-laser-wavelength alignment setup for MISI has been prototyped, and laser safety procedure discussions begun.
