Interesting business story too at their website: http://www.luxexcel.com/company/the-luxexcel-story/

If you skim through my SoOnCon 2011 talk slides, you can find some stuff on it.

They speak about a one-step-cad-to-optic process and no post processing necessary calling it printoptical technology.

http://spie.org/x8625.xml
Unfortunately, sounds like some of the holes need to be as small as 10 microns for visible wavelengths. Might be hard to laser-cut that…

Another fun property is that the chromatic aberrations are linear with wavelength so you get extreme dispersion.
