Hi Mikee,
My lens is made from Zinc Selenide and is AR coated on both sides - cleaning it is a delicate process which I really don't want to have to do very often so I use a 'co-axial, air assist' at all times and I have adjustable pressure / volume settings that I can select for different jobs. Because the lens assembly is always above ambient pressure during use it keeps the smoke out.
You can see the nozzle and just see the air supply line in this photo http://www.machsupport.com/forum/index.php?action=dlattach;topic=12444.0;attach=21034;image
