Zusammenfassung:This disclosure relates to a pulse oximeter. The pulse oximeter includes a light source emitting detecting light; a light acquirer spaced apart from the light source and so that the detecting light can get the light acquirer after passing through the object; a processor connected to the light acquirer; and a filter on the light path from the light source to the light acquirer. The filter includes a double band filter having center wavelengths of 660 nm and 940 nm. The double band filter can filter the unnecessary light and improve the accuracy of the pulse oximeter.
