Abstract
Method and apparatus are disclosed for mounting a second optical component on a first optical component using a spacer layer for forming a controlled gap between the two components. In a preferred embodiment, a CCD sensor is formed having a non-active area and an active area for detecting lightwaves. A spacer layer of an epoxy or similar material is formed on at least a portion of the non-active area of the sensor. A fiber optic faceplate is mounted on the spacer layer to form the controlled gap between the active area of the CCD sensor and the faceplate. The fiber optic faceplate has a predetermined index of refraction for passing lightwaves towards the active area of the sensor. A coupling compound, having an index of refraction which substantially matches that of the faceplate, is used to fill the controlled gap between the faceplate and the active area of the sensor.
