Hey folks,
I believe I now need to add spatial filters to my set up, any of you would still have some for sale?
Thanks !

Re: Looking for spatial filters
But now I have stopped using spatial filters and only use homemade lenses, they are much easier to clean and install. All my holograms are made like this.

Re: Looking for spatial filters
This lens type would for sure expand the beam, but would it also clean the N1+ order harmonics of the laser ? I sorta read it’s best to have a clean airy disk to work with my set up to have better resolution & more uniform exposure ?

I used a different approach for home made lenses, involving adhesives, photopolymers etc. But your idea seems much better.

In the Wiki you can find "John Klayer"s Spatial Filter Plan".
It's simple and very easy to use.
