Abstract: Technologies for an optomechanical system include an intermediate plate having a top surface with multiple tapped holes arranged in a grid. A pair of dowel pin holes surround each tapped hole in a linear pattern. Multiple optical blocks are coupled to the intermediate plate using dowel pins positioned in the dowel pin holes and corresponding dowel pin holes defined in the bottom surface of the optical block. Each optical block includes multiple optical elements coupled to the top surface of the optical block with dowel pins. A cryostat may be coupled to the intermediate plate. A cryo-package assembly is mounted inside a cryo chamber of the cryostat. The cryo-package assembly includes a cryo device such as an ion trap covered by a machined copper lid. The lid includes a meandering passageway to allow for differential pumping in order to achieve ultra-high vacuum within the cryo-package assembly.
