Abstract
An optical component assembly is created with reduced defects in the adhesion and alignment between the optical components. A first rigid optical component is placed into a cavity. A second rigid optical component is placed into the cavity such that it is supported by a first support device which prevents a first end of the second rigid optical component from contacting a corresponding first end of the first rigid optical component. Air is evacuated from a chamber formed between the first and second rigid optical components. The support of the first support device is removed so that the first end of the second rigid optical component comes into contact with the first end of the first rigid optical component with a layer of adhesive material sandwiched therebetween. A force is applied to urge surfaces of the first and second rigid optical components toward one another to improve adhesion between the two.
