Patent number: 7930814Abstract: A method for manufacturing a septum polarizer includes dispensing a layer of adhesive on a first contact surface of a first substrate, attaching the first substrate to a second substrate to form a combined structure, and elevating the combined structure to a first temperature that is above a first cure temperature of the adhesive for a predetermined period of time. The method further includes after attaching the first substrate to the second substrate, applying a continuous metallization coating over each outer surface of the attached first and second substrates, and elevating the combined structure and metallization coating to a second temperature, thereby curing the metallization coating without degrading the layer of adhesive. The metallization coating has a second cure temperature that is lower than the first cure temperature of the adhesive, and the second temperature is above the second cure temperature and below the first cure temperature.Type: GrantFiled: July 26, 2006Date of Patent: April 26, 2011Assignee: Raytheon CompanyInventors: Mark B.

Patent number: 7098396Abstract: A metal plate (126) has a plurality of openings (127) extending through it, and is cleaned using a wet hydrogen process (157). Glass windows (106) are then placed in the openings, and are each fused to the metal plate by heat (231) in a manner so that each window projects outwardly on each side of the plate. Both sides of each window are then simultaneously ground and polished (232). Exposed surfaces of the metal plate are electroplated with nickel and gold (236). One or more coatings (41, 46, 47) are applied to one or both sides of each window. Several sections are then cut from the assembly, each of which can serve as a lid (17) for an optical apparatus (10).Type: GrantFiled: June 7, 2004Date of Patent: August 29, 2006Assignee: Raytheon CompanyInventors: Mark B.

Patent number: 6974517Abstract: An apparatus (10) includes a digital micromirror device (16) disposed within a housing (11) that has an opening (13) hermetically sealed by a lid (17). The lid includes a radiation transmissive window (22) with peripheral edges fixedly coupled by an annular sealing section (23) to a metal frame (21). The sealing section engages a frame surface oxidized in a wet nitrogen furnace. The sealing section melts at a temperature lower than the window or frame. The sealing section includes two center rings (151, 152) made of sealing glass that are respectively bonded to the window and frame and to each other. The sealing section also includes inner and outer rings (152, 157, 158) made of sealing glass and disposed on opposite sides of the center rings to protect the center rings from environmental factors.Type: GrantFiled: June 13, 2001Date of Patent: December 13, 2005Assignee: Raytheon CompanyInventor: Mark B.
