=====8/25/2016 Simplified PhotoLithography Tests=====
I have removed all optics except one mirror, one lens, and the interference platform. The platform can now rotate although rotation still remains unmeasured. 

==Sample S1==
2.5 min exposure, Perfect split rotation

The new setup is giving grating lines but on a order of magnitude 100x the one we want. Images were taken at 5x magnification.

==Sample S2==
4 min exposure, Perfect split rotation.

The lines appear to be part of a large set of concentric circles. 40-25um between with a center near where the optical axis would hit the interference apparatus.
