Lenses received! The 2 405-G-1/2 lenses are in perfect condition. Couldn't be happier with them. The 650-g-2 lens however is in pretty awful shape. The spot produced makes a distinctive x around the spot along with a nice amount of spatter. I was planning on using this lens for the 1W 638nm laser I have here but this lens is unusable. What do you suggest? Maybe I can buy just the lens part from somewhere for a cheaper price since I already have the custom lens nut.
I messaged Jayrob but I just want to make sure this is where the lens came from. Thanks

Dang! Wish I would have waiting for a reply before spending $7 more than I needed to. No biggie. Thanks for the link. Yeah it was the 500mW Mitsu diode.
 
Luke, You can clean the lens.


Send it to me and Ill clean it for you..

SO long the lens is not scratch It will be like brand new again.:D

PM if your intrested...
 
Yeah if you think you can get it working again I will mail it out to you asap. That would be great! When/if you do get it back to normal you can go ahead and keep it. I owe you one. But yeah I am thinking it might be scratched as my attempts to clean it did nothing. Maybe you have a better method than I do. Probably as mine mostly involves a micro-fiber cloth.

I have enough Lenses.:D My enjoyment comes from helping other.;)

For future reference Never use a micro-fiber cloth to attempt to clean a lens. It will only make it 10x worse.


THe best way i found to Clean G Lenses is with ISOPROPYL Alcohol and a Couple of Q-Tips. "Make sure th Q-tips are the Clean kind that have no Lotions or chemicals on them as that will just make it worse again"


Use atleast 91% ISOPROPYL Alcohol....

First clean the lens with a Q-tip that has been dipped in ISOPROPYL alcohol. Make sure the Q-Tip is not dripping wet but just enough on it so it appears wet.

After this Wait 5 seconds then Quickly use a Dry Q-tip and dry up the lens.


DO both sides and thats it.

I think a video is in do for you all.:D


I swear G lens are the only lenses that are cleanable. I tried many times to clean 3 element lenses but it just always makes it worse. Must be the cheap coating on them.

^^^I would not try the above unless you know what you are doing or you dont care if you ruin your lens. It works perfect for me because I know how to do it but some might not get it just right. So at your own Risk as they say.:D

I have been also looking for personal lens cleaning kits but i have not found anything yet.:(

That is actually the first thing I tried and my go to method of cleaning lenses but when that didn't work I attempted to vigilantly rub the lens with the microfiber cloth. Also to no avail.
