That is the right call for shipping, since a bonded optic arrives seated correctly and cannot shift in transit. Once the machine is running, though, it means the lens and the bracket are permanently one part.\u003c\/p\u003e\n\u003cp\u003eThis reusable bracket changes that. It clamps a standard 20mm ZnSe lens mechanically instead of bonding it, so a worn or damaged lens costs you the price of the optic and nothing else.\u003c\/p\u003e\n\u003ch3\u003eThe focal length hack\u003c\/h3\u003e\n\u003cp\u003eThe bigger reason to run a reusable bracket: you can swap focal lengths.\u003c\/p\u003e\n\u003cp\u003eEvery 20mm ZnSe lens drops into the same slot in your laser head, so switching from a 2.5\" to a 3\" lens moves your focal point roughly half an inch further out without any other modification.
