Abstract
An image sensor sandwich having a linear sensor and a color filter is created that has the spacing between the sensor and the filter controlled to a very high tolerance by controlling the diameter of the glass beads within a mixture that is placed between the filter and the sensor. The mixture provides a simple, quick and economical spacing device that can be cured with few tools and requiring little time. The method and apparatus of mounting filters on sensors, comprises: providing upon select predetermined areas of a sensor a mixture of an ultraviolet curable resin and glass beads, the glass beads having an essentially uniform diameter, and further providing a light filter upon the sensor and the mixture such that the filter remains at a fixed height above the sensor, the fixed height being determined by the essentially uniform diameters of the glass beads; providing an ultraviolet light; and curing the mixture between the sensor and the filter with the ultra violet light.
