Hi friends,

I have a Universal Laser systems 40watt CO2 laser I use at my house.
I need to replace the ZnSe beam window that measures approx 12-12.5mm diameter and 2-3mm thickness. It looks to be flat on both sides (not meniscus or plano-convex).

It's easy to find replacement lenses and mirrors online, but i'm having a harder time finding this beam window.

"beam window" is the term given to the part by universal laser systems company, but i've also seen on other random sites like ebay, aliexpress, etc terms like "window protector" or "beam shield" etc...

Anyway...does anyone have any idea of where I can find this replacement part so i can just reglue it into position myslef vs shelling out $190 for a replacement "beam window" from ULS directly? I always DIY when I can.

I've replaced all the mirrors and lenses myself, but this is the last piece i need to replace due to a damaged spot on it.

I attached a picture of the beam window and housing it sits in.

Thanks!
