Claim 0:
1. A system comprising:
an emitter;
a detector;
an upper housing; and
a lower housing affixed to the upper housing, wherein the lower housing comprises:
a first portion that is optically opaque to a first wavelength of light; and
a second portion that is transparent to the first wavelength of light;
wherein the first portion of the lower housing comprises:
an inner surface facing the upper housing;
an outer surface opposite the inner surface;
a first window opening having a first edge, a second edge, a third edge, and a fourth edge;
a second window opening having a fifth edge, a sixth edge, a seventh edge, and an eighth edge, wherein the third edge is adjacent to the fifth edge; and
an optical baffle that extends upward from the first portion of the lower housing, wherein the optical baffle is:
adjacent to the first edge,
adjacent to the fourth edge,
between the third edge and the fifth edge,
adjacent to the sixth edge, and
adjacent to the seventh edge; and

wherein the second portion of the lower housing is disposed within the first portion and comprises:
a first side that contacts the inner surface of the first portion;
a second side opposite the first side that faces away from the first portion;
a first extension positioned at least partially within the first window opening;
a second extension positioned at least partially within the second window opening; and
a first opening proximate to the first extension and the second extension, wherein the optical baffle of the first portion extends through the first opening of the second portion, wherein the optical baffle extends beyond the first side and the second side of the second portion, and wherein a portion of the optical baffle that extends beyond the first side and the second side extends toward the upper housing;
wherein the emitter and the detector are positioned between the second portion and the upper housing, and wherein the portion of the optical baffle that extends beyond the first side and the second side and toward the upper housing is positioned between the emitter and the detector.
