Abstract
Light-blocking structures for optical physiological parameter measurement devices or sensors are disclosed. Such structures may include barrier walls and protrusions that further include intermeshing surface profiles designed to promote light-blocking capabilities at small scales to offset potential gaps that may occur due to assembly tolerance stack-ups.
