REVISION DATE: 09-Dec-2015 14:45:56

Below are the images taken for this experiment.

Diffuser options: 
acrylic diffuser = the original acrylic diffuser installed on the SQM, which won’t pass the UV we’d like to have
GM01 = 10um sandblast
GM02 = sided bead blast
GM03 = Al2O3 sandblast 300 mesh 60 psi 12” distance
GM04 = 2 sided lap by hand 70 um silicon carbide
opaque quartz = a smaller diameter piece of commercial opaque quartz that will not fit into the SQM until I make an adaptor/holder. So I just held it between the camera and the SQM.
