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. The arrangement of an opto-electronic component within an optical sensor receive module is improved by masking the receive module lens with an opaque member to create a masked lens leading edge that is aligned with a leading edge of the opto-electronic component.
