How old are you?
OK some common sense advice in case this is not a joke post and you actually can not figure out such a simple thing for whatever reasons.
Apparently you did not really look for lenses on the Sanwu web site.
They are all for sale here:
https://www.sanwulasers.org/product/lenses
PS the lenses are also listed at the bottom of the Spiker page,
You will also find the lenses offered at the bottom of page on every model laser Sanwu makes the web site--
So, either you did not look at the site, your eyes were closed, you were not looking at the screen with the Sanwu pages, or this has to be an "I am completely dysfunctional and need an LPF babysitter, help me" joke post.
An 8 years old could have found the lenses is several places on the Sanwu site in 10 seconds or less.
Does LPF look like LPF is the Sanwu warranty Dept.? lol
Email Sanwu and tell them what happened and ask if it is covered under the warranty or if you need to buy a lens and replace it.
If you can't change the lens yourself and want Sanwu to do it I am sure you can send it to them for repair--that is another choice
