摘要： According to one aspect of the present invention, a method of making a lens assembly with a plurality of lens arrays having a plurality of lenslets and at least one spacer having a plurality of holes, includes the steps of (i) arranging at least two lens arrays and the spacer, such that the spacer is located between the two lens arrays and the lenslets of one of the two lens arrays overlay the lenslets of another one of the two lens arrays and, the holes of the spaces are located between the corresponding lenslets of the two lens arrays; (ii) fixedly attaching the lens arrays and the spacer to one another to form an array assembly; and (iii) dividing the array assembly to create a plurality of individual lens systems. According to another aspect of the present invention, the optical assembly includes at least two lens arrays and at least one spacer with a plurality of holes. The spacer is located between the two lens arrays and is fixedly attached to the two lens arrays. The spacer has a thickness of 0.05 to 0.5mm. The lens arrays have a plurality of lenslets of no more than 1 mm in diameter. It is preferred that the lens arrays have a largest dimension of at least 5mm.

摘要： A method for making working mold tools for use in a compression molding process for molding optical glass elements from high temperature glasses having T g 's in the range of from 400°C to 850°C. An yttria aluminosilicate glass is fabricated by traditional melting and casting processes to thereby make an amorphous base material having a minimum apparent viscosity of 10 15 poise at the temperature at which the optical glass elements are to be molded. A mold preform is made from the base material. A first surface figure for the optical element to be molded with the working mold tool is defined. A second surface figure for a master mold tool and a third surface figure for the working mold tool are computed based upon the first surface figure and the coefficients of thermal expansion of the optical element, the master mold tool, and the working mold tool, the temperature at which the working mold tool is molded, and the temperature at which the optical element is to be molded. A master mold tool is then ground and polished to achieve the second surface figure. The working mold tool is then molded from the mold preform using the master mold tool.
