Abstract: An optical system includes an optical bench defining a mounting surface, an objective lens mounted to the optical bench, and an image intensifier tube. The image intensifier tube includes: (i) a housing defining an interior region and a mounting surface, and (ii) a photocathode bonded to a glass faceplate defining a faceplate surface, wherein the photocathode is positioned within the interior region of the housing, and wherein the mounting surface of the housing resides on the same plane as the faceplate surface. The mounting surface of the optical bench is mounted onto the mounting surface of the image intensifier tube housing such that the mounting surface of the optical bench resides on the same plane as the faceplate surface and the faceplate surface of the faceplate is the surface of the faceplate that is positioned closest to the objective lens.

Abstract: Disclosed is an improved mounting and securing device. The device provides for attachment at least one elongate object to a surface and includes a diaphragm spring and an oval fir tree mount. The device is secured to and prevents rotation in an oval or slot shaped hole in a mounting surface. The oval fir tree mount has a tapered tip and a substantially oval shape. Fir tree branches are attached to an oval shaped trunk at various elevations or staggered heights. The diaphragm spring includes a flexible umbrella extending toward the fir tree branches. The diaphragm spring provides tension and resistance when the fir tree mount is inserted into a mount hole formed in a supporting surface such as a panel. The flexible spring combined with the staggered height branches allow the device to be securely retained in different mounting hole thicknesses. The substantially oval configuration prevents rotation.

Abstract: In an optical system including an optical bench and an imaging device that is configured to be mounted to the optical bench, a method of aligning the imaging device on the optical bench includes the steps of: (1) inserting an alignment pin extending from a mounting surface of either the optical bench or the imaging device into a hole defined in the other of the optical bench and the imaging device; (2) aligning the imaging device with respect to a target image by translating and/or rotating the imaging device on the mounting surface of the optical bench while the pin is inserted in the hole to meet pre-defined center pixel, scan line and/or resolution requirements of the optical system; and (3) applying epoxy to the pin and the hole to mount the optical bench to the imaging device.

Abstract: Disclosed is an improved mounting assembly for securely supporting elongated items against a surface. The assembly includes a device to attach at least one elongate object to the mount, a spring section, and a mount section. The mount section is in the form of a rectangular fir tree mount. The rectangular fir tree mount has a tapered tip and a generally rectangular shape. The center segment of the rectangular fir tree mount includes a number of curved branches. The spring section includes flexible springs extending downwardly from the mount. The flexible springs provide tension and resistance when the mount is inserted into a supporting surface. The flexible springs and the branches allow the rectangular fir tree mount to be utilized on panels of varying thicknesses.
