Hi All,
Recently purchased 2 anamorphic prisms from Thorlabs.
Just testing Oclaro 638nm (HL63193MG) 700mw on 3-element glass from DTR trying to obtain a better beam.
-What have surprised me: I obtain the same results with 2 prisms than with only 1 prism
PLEASE see pics attached!! Measures are taken 21ft (6,5m) far.
So, why the need to use 2 prims? these are not cheap... Also, less losses with only 1 prism...
Any ideas??
Thank you so much
