  • Publication number: 20220143905
    Abstract: An additive manufacturing device may include a laser source configured to generate a laser beam, a build material holder configured to hold an additive build material, a controllable deflector having a first scan rate, an AOD having a second scan rate faster than the first scan rate, and a controller. The controller may be configured to control the controllable deflector and the AOD to scan the laser beam relative to the build material holder to additively manufacture a workpiece in successive layers from the additive build material.

  • Publication number: 20210254645
    Abstract: An acousto-optic device may include an acousto-optic component carried by a chassis, and a fastener assembly for removably securing a cover to the chassis. The fastener assembly may include a base sleeve having an enlarged head, and a tubular body and extending through a cover passageway. The fastener assembly may include a retainer sleeve having a threaded interior secured to the threaded exterior of the base sleeve to define an anchor member, the anchor member having a threaded interior. The fastener assembly may further include a fastener, a shaft having a threaded exterior opposite the enlarged head and to be threaded through the threaded interior of the anchor member to capture the fastener to the cover and movable through the chassis passageway for removably securing the cover to the chassis.

  • Publication number: 20210157180
    Abstract: An acousto-optic system may include a laser source, and an AOM coupled to the laser source and having an acousto-optic medium and transducer electrodes carried by the medium. The acousto-optic system may also include an interface board with a dielectric layer and signal contacts carried by the dielectric layer, and connections coupling respective signal contacts with respective transducer electrodes. Each connection may include a dielectric protrusion extending from the AOM, and an electrically conductive layer on the dielectric protrusion for coupling a respective transducer electrode to a respective signal contact.

  • Publication number: 20200393633
    Abstract: The optical system includes a base having a groove and an adjacent slot therein. The system also includes at least one optical cell slidably alignable along the groove, and at least one clamp comprising a lower end and an upper end. The lower end is slidably alignable along the slot and is secured at a set location so that the upper end secures the at least one optical cell along the groove. The slot may extend parallel to the groove. The clamp may include at least one preloaded fastener arrangement securing the lower end of the clamp to the base. The preloaded fastener may include a bolt, a spring biasing the bolt, and a threaded backing plate within the slot and receiving the bolt.
