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 size of at least one of emit and receive module lenses of an optical sensor, and the offset between the opto-electronic component and the respective lens of at least one of emit and receive modules is decreased to increase amplitude of the signal received by the receive module from the emit module.
