Just curious, can someone please show me how does look like the grating pattern of the "axicon" to generate a lattice light-sheet? A picture or general scheme will be greatly appreciated:)
Hi, Aaron
"Spatial light modulator" — that's the correct name of the element I was looking for;)
Quite interesting device and seemingly can be produced by photolithography.
It should look like some of these:

Was wondering about the purpose of the annulus, but could find about it on the original Betzig's paper (doi:10.1126/science.1257998)
Thank you!
