Abstract:
1. An optical assembly comprising: an optical device to generate a collimated light beam; a mirror; an array of micro lenses, each of the micro lenses corresponding to one of electronic devices in an array; an array of filters disposed between the mirror and the micro lenses; a substrate on which the optical device, the mirror and the micro lenses are bonded, where the mirror is tilted with respect to the array of filters and the array of micro lenses to ensure that each of the micro lenses corresponds to a light beam coming from or going to a corresponding one of the filters; and a compensative plate inserted between the array of micro lenses and the array of filters to correct optical errors caused by one or more of the optical device, the mirror, the filters, and the micro lenses, wherein the compensative plate is provided to correct the optical errors in one or more but not all of light paths between the array of micro lenses and the array of filters.
