On your page your sell this “Cloudray Output Protective Connector For Raycus Fiber Laser Source 0-4KW”, link Cloudray Output Protective Connector For Raycus Fiber Laser Source 0-4 – Cloudray Laser
I have a Rayus Fiber laser from you and i do not understand where I must install this protective lens.
