Abstract
A light sensor including a substrate and one or more low profile baffle plates, the baffle plates including collimator holes to allow intended light to strike the light detector of the substrate while preventing extraneous light from striking the detector. The baffle plates are disposed above the substrate, on a shroud, which covers a portion of the substrate but allows intended light to pass through the collimator holes onto the light detector. By stacking baffle plates having a thin, low profile, one on top of another upon the shroud, extraneous light striking the material at an angle between the collimator holes cannot enter the sensor while intended light in the substantial front of the sensor enters the sensor through the collimator holes and can be detected by the light detector.
