Zusammenfassung:An optical sensor module includes a housing, first and second optical emitters within the housing, and an optical detector within the housing that is positioned between the first and second optical emitters. The housing includes respective first and second windows of optically transparent material that overlie the first and second optical emitters, and also includes a third window of optically transparent material that overlies the optical detector. The third window includes opposite first and second ends and opposite first and second sides, and at least one of the first and second sides is curved inwardly. Both of the first and second sides of the third window may be curved inwardly such that the third window has an hourglass shape.
