<p>A pulse oximeter sensor having an opaque, metalized layer (16) to shield from ambient light. The metalized layer (16) surrounds the area of the light detector (32). In one embodiment, the sensor has a transparent portion (12), with the opaque, metalized layer (16) covering only the portions around the light detector (32) and other areas, such as a strip extending between the light detector (32) and the emitter (36). In a preferred embodiment, the opaque, metalized layer (16) is a strip which has a widened portion in the area around the light detector (32).</p> |
