Pressured air to clean lens

[ISP cash cow]

We deal with optical scientific equipment with lenses and filters. We have a procedure of cleaning them which does use compressed gas as well as lens cleaning paper and lens cleaning liquid.

we usually use the compressed gas before wiping with the lens paper and liquid just to remove any small particles that may scratch the filter, and then we clean with the lens paper and lens cleaning liquid (it is usually just an alcohol based solution).

Using the compressed gas can you just need to shake well before use and the first couple of squirts do not do on the lens do it in the air as this will release all the moisture build up in the can. Once you can see the air blowing is clear you can use it on the lens.

Also using a t shirt on a lens is not advisable. You may think it is soft and cushy but under a microscope it is seriously rough and can scratch surfaces or damage the protective film on the lens. That is also why normal tissue is also a bad idea. There was a reason why lens paper was invented and is used.

The best way to clean lenses is to use 1) Lenspen, which is designed to clean lenses or 2) a lens cloth, soft cloth that some photography shops sell. The cloth is similar to the cloth to clean spectacles, but I suspect it is even softer. Compressed air will only lead to condensation on the lens, which will lead to dirt getting stuck to the lens.
