Default Cleaning sanwu pocket

I was wondering if I were to clean the lens on my sanwu pocket, what would be the best way to do so without harming the laser?

Did you bother searching at all? There's already a bunch of threads on this topic.

This page is good: https://www.thorlabs.com/tutorials.cfm?tabID=26066

As is this:
https://marketplace.idexop.com/Front...ng_methods.pdf

I usually stick with pure Isopropyl alcohol (Lab grade) and micro-fiber cloths. Anything other than lab grade isopropyl is probably best avoided - it can leave residue on the lens. Acetone and distilled water would work well too, although I've never used that. Of course, that's for glass optics (Which I believe the pocket series uses). Plastic optics are harder to clean as they are more prone to scratches and such.

There's also First Contact(TM) optics cleaner - that stuff is great, although it's fairly expensive.

Other's just use compressed air to remove dust - obviously that won't work for grease marks or fingerprints.

Of course, best to remove the lens from the laser before using any solvents.

Edit: Link to Edmunds - they are one seller of First Contact: http://www.edmundoptics.com/lab-prod...solution/3510/

The stuff is good and you really don't need much to clean an optic. Works better than anything else I've seen or used.

Worth it if you'll get good use out of it IMO.
