How to replace the lens:
1- Remove the lens housing from the laser module. If there is glue, soak it in acetone for 1-2 hours to soften the glue. Slide the lens out of the housing.
2- Add high temperature silicone or sealant to adhere the lens to the case. (Don't add too much, just a little drop is enough). This is an option.
3- Carefully insert the lens, make sure there is no glue in the center of the lens and let it dry according to the glue instructions (Do not put the housing back into the laser until it is completely dry. Skip this step if you have not glued the lens.
4- Put the o-ring (if purchased) on the top of the lens, if you want to eliminate the gap between the new lens and the nozzle. While twisting the lens housing on the nozzle, make sure that the o-ring is centered.
5- Put the lens housing back on the module and enjoy.
