Abstract
An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. An optical sensor connected to a housing of a medical device includes a circuit board, an opto-electronic component, a wall, a lens, and a ferrule. The circuit board is arranged within the housing. The opto-electronic component is mounted on a surface of the circuit board. The wall protrudes from the surface of the circuit board and surrounds the opto-electronic component. The lens is offset from the surface of the circuit board. The ferrule is connected to the housing, the lens and the wall. An inner surface of the wall mates with an outer surface of the ferrule.
