Vacuum compensated mirror mount assembly

Claim 1

A vacuum compensated mirror mount for a laser mirror which requires liquid cooling, comprising: a. a base having a horizontal portion and a vertical portion, with said vertical portion having a front face and a back face, and with said vertical portion having a cylindrical shaped aperture therethrough and two similar and substantially smaller apertures also therethrough; b. a first bellows subassembly which includes: 1. an open-ended right-circular cylinder first bellows having a front end and a back end; 2. a first flange ring affixed to the front end of said first bellows: 3. and, a second flange ring affixed to the back end of said first bellows, with said second flange ring having three tabs circumferentially spaced thereon and extending outwardly therefrom; with said first flange ring and said first bellows passing into and through said cylindrical shaped aperture of said base, and said second flange ring removably attached to said vertical portion of said base by said three tabs of said second flange ring; c. a mirror support, with a mirror suitably located thereon, and removably attached thereto, positioned rearward of, and internal of, said open-ended right-circular cylinder first bellows, with said mirror support having a back end to which a flange ring is affixed, and with said mirror support having means for conducting a liquid coolant to and from the mirror; d. a second bellows subassembly which includes: 1. an open-ended right circular cylinder second bellows having a front end and a back end; 2. a first flange ring affixed to the front end of said second bellows; 3. and, a second flange ring affixed to the back end of said second bellows; with said first flange ring of said second bellows subassembly removably attached to said flange ring of said mirror support; e. a cavity side plate disposed to the front of said base, and having a cylindrical shaped aperture therethrough around the periphery of which is removably attached the said first flange ring of said first bellows subassembly, and having two struts in parallel spaced relationship which are attached at one end to said cavity side plate and the other ends of which enter into and pass through said smaller apertures in said base; f. a sealing plate removably attached to said second flange ring of said second bellows subassembly and to said other ends of said struts of said cavity plate; with the longitudinal axis of said cavity sideplate aperture, of the cylindrical shaped aperture of said base, of said first bellows subassembly, of said mirror mount, and of said second bellows subassembly being coincident and also coinciding with the optical axis of the mirror removably connected to said mirror mount, and with the geometric center of said sealing plate also being on the coincident axis.
