l am planning to buy by AR coating machine. l do 10 Ar job per day. l am confused which AR coating machineis good ?

l can give u the processes for the machine types, but yuod need to be more specific for a better answer.

There is the Satis Ioncoat process. My understanding is that this is esentially a very thick silica layer which may also include some organic content. l do not know much about it.

There is also the Diaplas process, a plasma polymerization process. l think this might also be a Satis process but l know even less about it than the others.

l can say that in my experience the in-vacuo hard coating processes r relativly slow in comparison to either ex-vacuo hard coating processes (spin or dip coating) or a typical AR process. This means that the throughput of ur very expensive vacuum systems is dramatically reduced meaning the necessary capital investment for a fixed throughput goes way, way up.

The Old Leybold Safire Process is a Combination with A Hardcoat Layer Made by a SiO2 together, a Special Monomer & Water , & a conventional A.R. pack .
This kind of process is made using 2 E.B. gun & a old LEybold APS equipment (Advanced Plasma Source= something like a IOn gun .BUt more more strong).

One EB GUN is performed only for the SiO2 & the second is for the A.R. pack.

This kind of process is not so simple even if the result is excellent for CR-39 substrates.

Good Luck!
