Sanwu laser lenses (cleaning)

[varganorbert222]

I tried to look up exactly what lenses are in my lasers, but I got confused. I also have Sanwu Pocket laser and Guardian. Guardian has a clear lens, but Pocket has colored lenses. For example, the red laser has a blue lens. I think it's some sort of coating on it. My question is, what exactly are the lenses in the lasers, and how can I clean them?

Thanks!

You can get those hollow rubber balls with tips on them meant for blowing dust of camera lenses, they shouldn't damage the coating, I wouldn't clean them with any solvents, compressed cans of air included because of the volatile chemicals they use to drive the gas, there are lots of optical coatings that get damaged if you try to clean them.

That said they shouldn't need to be cleaned beyond maybe removing loose dust occasionally.

Thanks for the quick response! I didn't use any solvents. I bought a Lenspen MicroPro and a Hurricane Blower pump. I have to say they worked perfectly. First, I blew the dust off the lenses with the pump, then I brushed the lenses with the large brush of the lenspen, and finally I wiped the smudges off the lens with careful movements with the lenspen. The lens is as clean as when it was new. I can recommend Lenspen products for cleaning lenses! Of course, in my case there was no gross dirt on the lenses. After that, I think I only have to use the pump, because it is enough to blow off any loose dust. By the way, I needed the lenspen because I accidentally spit on the lens.

If I were you, I would invest in a electric duster, works well to remove any fine particles that can scratch the lens when wiping.

I grew up as a glazier in SoCal, I’ve been around glass since I can remember, 30+years.

99% alcohol works very well after a high pressure dusting has been done. And I’ve purchased 3 different Optic Lens cleaning solutions in the past 6-8 months. The best one I’ve found is called Sensei. I bought it online, i forgot where. But it works extremely well and doesn’t leave any film, as long as you use clean 100% cotton Qtips, use a small amount, apply by spraying the qTip.

My method is:

1.) High pressure air dusting with my electrical duster, which I only use for this purpose and keep in a bag while not in use to keep from attracting static dust.

2.) get fresh Qtips, also kept in a sealed bag, spray the Qtip 1x with the fine mist from the Sensei cleaning solution.

3.) wipe the lens using 1 direction motion, going back and forth will only spread and scratch your lens. I use either a clockwise or counterclockwise motion, I only switch direction when I switch Qtips.

4.) then I use atleast 2-3 more dry and clean Qtips with the same method as #3, making sure to press against the lense to get into the corners.

5.) this is all just for 1 side of the lens. I repeat the steps for the opposite side.

6.) and I always keep my lens capped. Get yourself some 15/16mm rubber clicky switch covers to use as a lens cap. I believe it’s the 16mm that fits perfectly on a standard lens focus peice? I also have the Survival Lasers extended focus peice on all my lasers as well. It really helps keep them cleaner during use.
