Abstract
Methods for cutting strengthened glass are disclosed. The methods can include using a laser. The strengthened glass can include chemically strengthened, heat strengthened, and heat tempered glass. Strengthened glass with edges showing indicia of a laser cutting process are also disclosed. The strengthened glass can include an electrochromic film.
Claims30
A piece of cut thermally-strengthened glass comprising:
- a thermally-strengthened glass substrate having a first surface, an opposing second surface, and a peripheral edge between the first surface and the second surface, the edge having indicia of a laser filamentation cutting process, wherein the indicia of a laser filamentation cutting process comprises a filamentation pattern defined by a series of regularly recurring substantially parallel filamentation traces.
An electrochromic device comprising at least one strengthened glass substrate having a first surface, an opposing second surface and a peripheral edge between the first surface and second surface, the peripheral edge having indicia of a laser filamentation cutting process, wherein the indicia of a laser filamentation cutting process comprises a filamentation pattern defined by a series of regularly recurring substantially parallel filamentation traces.
An insulated glass unit comprising:
- a first lite comprising a strengthened glass substrate having a first surface, an opposing second surface and a first peripheral edge between the first surface and second surface,
- a second lite comprising a glass substrate having a first surface, an opposing second surface, and a second peripheral edge between the first surface and second surface,
- a spacer element providing spatial separation between the first glass lite and the second glass lite,
- at least one of first peripheral edge or the second peripheral edge having indicia of a laser filamentation cutting process, wherein the indicia of a laser filamentation cutting process comprises a filamentation pattern defined by a series of regularly recurring substantially parallel filamentation traces.
